These devices contain two independent 4-input positive NOR gates. They perform the Boolean functions: Y = (A + B + C + D)\ or Y = A\ \x95 B\ \x95 C\ \x95 D\ in positive logic. The SN54HC4002 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC4002 is characterized for operation from -40°c to 85°C.

These octal buffers and line drivers feature the performance of the SNx4HC541 devices and a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout. The 3-state outputs are controlled by a two-input NOR gate. If either output-enable (OE1orOE2) input is high, all eight outputs are in the high-impedance state. The SNx4HC541 devices provide true data at the outputs.

The SNx4HC573A devices are octal transparent D-type latches that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. While the latch-enable (LE) input is high, the Q outputs respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up.

These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable (OE\) input can be used to disable the device so the buses are effectively isolated.
