| Latches | 1 | Obsolete | The 74FCT373T is an octal transparent latch that has 3-state outputs and is intended for bus oriented applications. When Latch Enable (LE) is high, the flip-flops appear transparent to the data and when LE is low, the data that meets the set-up time is latched. The 74FCT373T operates at -40C to +85C. (For Mil version, see 54FCT373T) |
| Logic | 4 | Active | The 74FCT374T is an 8-bit register that consists of eight D-type flip-flops with a buffered common clock and buffered 3-state output control. When the output enable (OE) input is low, the eight outputs are enabled. When the OE input is high, the outputs are in the high-impedance state. The 74FCT374T operates at -40 °C to +85 °C. For the Mil version, see 54FCT374T. |
| Logic | 1 | Obsolete | The 74FCT377T is an octal D flip-flop that has eight edge-triggered, D-type flip-flops with individual D inputs and O outputs. The common buffered Clock (CP) input loads all flip-flops simultaneously when the Clock Enable (CE) is low. The register is fully edge-triggered. The 74FCT377T operates at -40C to +85C |
| Clock Buffers, Drivers | 2 | Active | The 74FCT38072S is a low skew, single input to two output, LVCMOS clock buffer that offers a best-in-class additive phase jitter of sub 50fs. |
| Clock Buffers, Drivers | 1 | Active | The 74FCT38074S is a low skew, single input to four output, LVCMOS clock buffer that offers best-in-class additive phase jitter of sub 50fs. |
| Clock/Timing | 1 | Active | The FCT38075 is a 3.3V clock driver built using advanced CMOS technology. This low skew clock driver offers 1:5 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution. |
| Clock Buffers, Drivers | 14 | Active | The FCT3807/A 3.3V clock driver is built using advanced dual metal CMOS technology. This low skew clock driver offers 1:10 fanout. The large fanout from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. The FCT3807/A offers low capacitance inputs with hysteresis for improved noise margins. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution. |
| Integrated Circuits (ICs) | 2 | Obsolete | The FCT388915T uses phase-lock loop technology to lock the frequency and phase of outputs to the input reference clock. It provides low skew clock distribution for high performance PCs and workstations. One of the outputs is fed back to the PLL at the FEEDBACK input resulting in essentially zero delay across the device. The PLL consists of the phase/ frequency detector, charge pump, loop filter and VCO. The VCO is designed for a 2Q operating frequency range of 40MHz to f2Q Max. The FCT388915T provides 8 outputs, the Q5 output is inverted from the Q outputs. The 2Q runs at twice the Q frequency and Q/2 runs at half the Q frequency. The FREQ_SEL control provides an additional ÷ 2 option in the output path. PLL _EN allows bypassing of the PLL, which is useful in static test modes. When PLL_EN is low, SYNC input may be used as a test clock. In this test mode, the input frequency is not limited to the specified range and the polarity of outputs is complementary to that in normal operation (PLL_EN = 1). The LOCK output attains logic HIGH when the PLL is in steady-state phase and frequency lock. When OE/RST is low, all the outputs are put in high impedance state and registers at Q, Q and Q/2 outputs are reset. The FCT388915T requires one external loop filter component as recommended in Figure 3. |
| Integrated Circuits (ICs) | 3 | Active | The IDT74FCT521T is an 8-bit identity comparator that compares two words of up to eight bits each and provides a low output when the two words match bit for bit. The expansion input IA= B also serves as an active low enable input. The 74FCT521T operates at -40 °C to +85 °C. |
| Logic | 1 | Obsolete | The 74FCT540T octal buffer/line driver is similar in function to the FCT240T, except that the inputs and outputs are on opposite sides of the package. This pinout arrangement makes these devices especially useful as output ports for microprocessors and as backplane drivers, allowing ease of layout and greater board density. The 74FCT540T operates at -40C to +85C |
