SN74LVT244BZQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT244BZQNR is a 3.3-V ABT octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. Designed for low-voltage VCC operation, it provides TTL interface capability to 5-V systems. The device features non-inverting logic with eight input lines and eight output lines housed in a 20-pin BGA package. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of 2.3 ns at 3.3 V, high-level output current of -32 mA, and low-level output current of 64 mA.
