DESCRIPTION

The 74VCX16244 is a low voltage CMOS 16 BIT BUS BUFFER (NON INVERTED) 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. Any nG output control governs four BUS BUFFERS. Output Enable input (nG) tied together gives full 16-bit operation. When nG is LOW, the outputs are on. When nGis HIGH, the output are in high impedance state. This device is designed to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74VCX16244 LOW VOLTAGE CMOS 16-BIT BUS BUFFER (3-STATE) WITH 3.6V TOLERANT INPUTS AND OUTPUTS ORDER CODES PACKAGE TUBE T & R TSSOP 74VCX16244TTR TSSOP PIN CONNECTION
