Product details

Six inverters in a DIP — field-service staple

The Texas Instruments SN74AHCT04N is a hex inverter from the 74AHCT logic family. It packs six independent NOT gates into a single 14-pin DIP package, each with a single input and a standard push-pull output rated for 8 mA source and sink. The 4.5 V to 5.5 V supply range makes it a direct drop-in for 5 V TTL or CMOS systems — the input thresholds are TTL-compatible (0.8 V low, 2 V high), so it works with older 5 V logic without level-shifting. Propagation delay is 7.7 ns typical at 5 V with a 50 pF load, fast enough for most board-level glue logic, clock gating, or signal inversion.

The through-hole DIP package (14-DIP, 0.300" body width) is socket-friendly and field-replaceable — no hot-air station needed, no risk of tombstoning.

Active production, easy sourcing

Texas Instruments lists it as current production, and it is widely available through independent distribution.

Frequently asked questions

Can SN74AHCT04N replace SN74HC04N?

The SN74AHCT04N is a direct functional replacement for the SN74HC04N in 5 V systems — both are hex inverters in the same 14-DIP pinout. The AHCT variant has TTL-compatible input thresholds (0.8 V low, 2 V high) versus the HC's CMOS thresholds (0.3 Vcc low, 0.7 Vcc high), so in a mixed-voltage board the AHCT is the better choice when driving from TTL outputs. Propagation delay is similar (7.7 ns vs ~9 ns typical).

Is SN74AHCT04N compatible with 5V logic?

Yes — the SN74AHCT04N is designed for a 4.5 V to 5.5 V supply and its input thresholds are TTL-compatible, making it a direct fit for 5 V TTL and 5 V CMOS systems. The 8 mA output drive is sufficient for driving standard logic inputs or low-power loads.

What is the difference between SN74AHCT04N and SN74HC04N?

Both are hex inverters in the same 14-DIP package. The key difference is input threshold: SN74AHCT04N uses TTL-compatible levels (0.8 V low, 2 V high), while SN74HC04N uses CMOS levels (0.3 Vcc low, 0.7 Vcc high). In practice, the AHCT version is the better choice when driving from 5 V TTL outputs, and it maintains the same pinout and supply range.
