74ACT16245SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT16245SSCX is a 16-bit bus transceiver belonging to the ACT logic series. It features two non-inverting transceivers, each handling 8 bits of data, housed in a 48-pin SSOP package. The device operates with a supply voltage range of 4.5V to 5.5V and supports TTL input levels with CMOS output levels. Key electrical parameters include a maximum propagation delay of 8.4ns at 50pF load capacitance, and output drive capabilities of 24mA for both high and low states. It functions within an operating temperature range of -40°C to +85°C.
