74AHCT1G07GW,165

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74AHCT1G07GW,165 is a high-speed Si-gate CMOS non-inverting buffer featuring an open-drain output. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes the TSSOP5 (SOT353-1) plastic thin shrink small outline package with five leads and a body width of 1.25 mm. Designed for digital applications, it requires an external pull-up resistor to establish a logic HIGH level.

Buffers, Drivers, Receivers, Transceivers FAQ

Why is an external pull-up resistor necessary for this device?

The device features an open-drain output structure. Without an external pull-up resistor connected to the supply voltage, the output cannot actively drive a logic HIGH level, resulting in a floating state.

What distinguishes the AHCT variant from the AHC variant?

The AHCT variant utilizes TTL input switching levels and operates strictly within a 4.5 V to 5.5 V supply range, whereas the AHC variant uses CMOS input levels and supports a wider voltage range starting from 2.0 V.
