SN54AHC174, SN74AHC174 HEX D-TYPE FLIP-FLOPS WITH CLEAR are TI company's six D-type flip-flops with single-rail outputs. They can be used for buffer/storage registers, shift registers, pattern generators, etc.
The SN54AHC174 and SN74AHC174 are positive‑edge‑triggered D‑type flip‑flops that include a direct clear (CLR) input. They operate from 2 V to 5.5 V VCC and are intended for applications such as buffer/storage registers, shift registers, and pattern generators. The device transfers data present at the D input to the Q outputs on the rising edge of the clock, while the clear input forces the outputs low.
The family is offered in multiple package types (PDIP, SOIC, SSOP, TSSOP, TVSOP, etc.) with detailed electrical characteristics, timing parameters, and mechanical drawings provided. ESD protection complies with JESD‑22 standards, and thermal impedance values are listed for each package.
| Supply voltage range (VCC) | 2 V to 5.5 V |
|---|---|
