74FCT16245LTPA

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16245LTPA is a high-speed, low-power CMOS bus transceiver belonging to the 74FCT logic series. It features dual independent 8-bit channels or a single 16-bit configuration within a 48-pin TSSOP package. The device operates with a supply voltage range of 4.5V to 5.5V and supports TTL input and output levels. Key electrical characteristics include a maximum propagation delay of 3.5ns at 50pF load, with output drive capabilities of -24mA (high) and 24mA (low). It functions within an extended commercial temperature range of -40°C to +85°C.
