74ACT11245NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT11245NSR is an octal bus transceiver from Texas Instruments, utilizing Advanced CMOS (ACT) logic technology. It features eight non-inverting channels with three-state outputs, designed for high-speed data transfer in bidirectional applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-compatible input levels. Key electrical parameters include a propagation delay of approximately 10 ns at 5 V, with output drive capabilities of 24 mA for both high and low states. It is housed in a 24-pin TSSOP package and rated for operation between -40°C and +85°C.
