Product details

Six-bit D-type with master reset — 180 MHz edge rate

The Texas Instruments SN74AHC174D is a 6-bit D-type flip-flop in the 74AHC family, clocked at 180 MHz on a positive edge with a non-inverted output and a master reset function. It operates from a 2V to 5.5V supply, drawing only 4 µA quiescent current, and sinks or sources 8 mA per output. Propagation delay is 9.2 ns at 5V into 50 pF. The 16-SOIC package (3.90 mm body width) fits surface-mount assembly. Typical use: data latching, register storage, and synchronous bus buffering in industrial control, telecom, and general-purpose logic designs.

Lifecycle and compliance — active, RoHS3, no obsolescence risk

The SN74AHC174D carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy schedule applies.

Frequently asked questions

How does SN74AHC174D compare to 74HC174?

The 74AHC series offers higher clock frequency (180 MHz vs typically 50-100 MHz for 74HC) and lower quiescent current (4 µA vs typically 80 µA for 74HC), making it a better fit for higher-speed or lower-power designs. Pinout and function are similar.

Is SN74AHC174D RoHS compliant and lead-free?

Yes, the SN74AHC174D is ROHS3 compliant.

What is the function of SN74AHC174D?

It is a 6-bit D-type flip-flop with positive-edge trigger, master reset, and non-inverted output.
