DESCRIPTION
The 74ALVCH162240 is a low voltage CMOS 16 BIT BUS BUFFER (INVERTED) fabricated with sub-micron silicon gate and five-layer metal wiring
2
C
MOS technology. It is ideal for low power and very high speed 1.65 to 3.6V a pplicat ions; it can be interfaced to 3.6V signal environment for both inputs and outputs. Any nG BUFFERS. Output Enable input (nG
output con trol governs four BUS
) tied together gives full 16-bit operation. When nG nG
is LO W, the outputs are enabled. When
is HIGH, the output are in high impedance state. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. This device is designed to be used with 3 state memory address drivers, etc. The device circuits is including 26series resistance in the out puts. These res ist ors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against stat ic discharge, giving them 2KV ESD immunity and t ransient excess voltage.
