Product details

8-bit shift register for 5V logic expansion

The SN74AHCT595PWR: The single-element 8-bit architecture accepts serial data and latches it to parallel outputs, with a tri-state output enable for bus sharing.

The 4.5V–5.5V supply range is tight—this part is designed for regulated 5V rails, not 3.3V or battery-powered circuits. If your system runs a 5V bus, the AHCT family gives you the input thresholds (TTL-compatible) and output drive of a standard 5V logic part.

The supplier device package is 16-TSSOP; the listing also supports Cut Tape (CT) for prototyping quantities alongside Tape & Reel for production.

Frequently asked questions

Can SN74AHCT595PWR replace 74HC595?

The SN74AHCT595 is pin-compatible with the 74HC595 and offers the same 8-bit shift register function. The key difference is the input threshold: AHCT uses TTL-compatible levels (0.8V/2.0V), while HC uses CMOS thresholds (0.3Vdd/0.7Vdd). In a 5V system driven by a 5V microcontroller, both work; the AHCT variant is often preferred for mixed-voltage or TTL-driven buses.

Is SN74AHCT595PWR RoHS compliant?

Yes, the SN74AHCT595PWR is ROHS3 compliant, meaning it meets the latest EU RoHS directive without exemptions for lead or other restricted substances.
