The SL74HC374 is a high-performance silicon-gate CMOS octal 3-state noninverting D flip-flop. It has the same pinout as the LS/ALS374. The device inputs are compatible with standard CMOS outputs, and with pull-up resistors, they are compatible with LS/ALSTTL outputs. Data meeting the setup and hold time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled.
The SL74HC374 is an octal 3‑state non‑inverting D flip‑flop compatible with LS/ALS374 pinout. It features CMOS, NMOS, and TTL compatible inputs and outputs, with an output‑enable pin that places the outputs in a high‑impedance state when high.
Key specifications include an operating voltage range of 2.0 V to 6.0 V, maximum output current of 335 mA per pin, and a maximum clock frequency of up to 6 MHz. The device is rated for storage temperatures from –65 °C to +150 °C and includes protection circuitry against static discharge.
