DESCRIPTION

The 74VCX162245 is a low voltage CMOS 16 BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and five-layer metal wiring C 2MOS technology. It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. This IC is intended for two-way asynchronous communication between data buses; the direction of data transmission is determined by DIR input. The two enable inputs nG c a nb eu s e dt od i s a b l e the device so that the buses are effectively isolated. The device circuits is including 26Ω se- ries resistance in the A port outputs. These resis- tors permit to reduce line noise in high speed ap- 74VCX162245 LOW VOLTAGE CMOS 16-BIT BUS TRANSCEIVER (3-STATE) WITH 3.6V TOLERANT INPUTS AND OUTPUTS ORDER CODES PACKAGE TUBE T & R TSSOP 74VCX162245TTR TSSOP PIN CONNECTION
