SN54AHC374, SN74AHC374 are octal edge-triggered D-type flip-flops with 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels of the data (D) inputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly.
The SN54AHC374 and SN74AHC374 are octal edge‑triggered D‑type flip‑flops featuring 3‑state outputs that can drive highly capacitive or low‑impedance loads. They are suitable for buffer registers, I/O ports, bidirectional bus drivers, and working registers.
