74ACT16541TTR

Buffers, Drivers, Receivers, Transceivers Overview

The STMicroelectronics 74ACT16541TTR is a 16-bit bus buffer with 3-state outputs, fabricated using advanced sub-micron silicon gate C2MOS technology. It features two independent 8-bit sections with separate output-enable signals (nG1 and nG2). The device operates within a supply voltage range of 4.5V to 5.5V and provides symmetrical output impedance with minimum drive currents of 24mA for both high and low states. It offers high-speed performance with a typical propagation delay of 4.8ns at 5V and includes protection circuits against static discharge.
