The SN74AHCT165-Q1 device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state outputs. Separate clocks are provided for both the shift and storage registers. The shift register has a direct overriding clear ( SRCLR) input, a serial (SER) input, and a serial output for cascading. When the output-enable ( OE) input is high, all outputs except QH′ are in the high-impedance state.

These 16-bit buffers and bus drivers provide a high-performance bus interface for wide data paths. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1\ or OE2\) input is high, all corresponding outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54AHCT16540 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AHCT16540 is characterized for operation from -40°C to 85°C.

The 'AHCT16541 devices are noninverting 16-bit buffers composed of two 8-bit sections with separate output-enable signals. For either 8-bit buffer section, the two output-enable (1OE1\ and 1OE2\ or 2OE1\ and 2OE2\) inputs must both be low for the corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 8-bit buffer section are in the high-impedance state.
