1 / 6 page © 1999 Fairchild Semiconductor Corporation DS500345 www.fairchildsemi.com August 1999 Revised October 1999 74ACT16646 16-Bit Transceiver/Register with 3-STATE Outputs General Description The ACT16646 contains sixteen non-inverting bidirectional registered bus transceivers providing multiplexed transmis- sion of data directly from the input bus or from the internal storage registers. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The DIR inputs determine the direction of data flow through the device. The CPAB and CPBA inputs load data into the reg- isters on the LOW-to-HIGH transition. Features s Independent registers for A and B buses s Multiplexed real-time and stored data transfers s Separate control logic for each byte s 16-bit version of the ACT646 s Outputs source/sink 24 mA s TTL-compatible inputs Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Logic Symbol Connection Diagram FACT ™ is a trademark of Fairchild Semiconductor Corporation.
