SN74AHCT244DGVR TI Buffer/Driver | 20-TVSOP | 8-Ch, Non-Inverting, 5V Tolerant

Product Overview

The SN74AHCT244DGVR is a high-performance octal buffer and line driver from Texas Instruments, designed for 5V systems. It features eight non-inverting buffers with 3-state outputs, ideal for driving bus lines or buffering memory address registers. Housed in a compact 20-TVSOP package, this device offers a balance of speed and power efficiency, with a typical propagation delay of 7.5 ns and low power consumption of 40 µA (max) quiescent current. It is fully specified for industrial temperature ranges (-40°C to 85°C) and is compatible with TTL levels, making it suitable for mixed-voltage environments.
