74ACT16245TTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74ACT16245TTR is a 16-bit bus transceiver with 3-state outputs manufactured by STMicroelectronics. It operates within a supply voltage range of 4.5V to 5.5V and features a typical propagation delay of 4.9ns at VCC = 5V. The device provides symmetrical output impedance with minimum drive currents of |IOH| = IOL = 24mA. Quiescent supply current is limited to a maximum of 8μA at 25°C. Input levels are compatible with TTL standards, specifying a minimum high-level input voltage (VIH) of 2V and a maximum low-level input voltage (VIL) of 0.8V. It supports 50Ω transmission line driving capabilities.
