DESCRIPTION:
Potato Semiconductor’s PO74G164245A is designed
for world top performance using submicron CMOS
technology to achieve 1GHz TTL /CMOS output
frequency.This Octal bus buffer gate is designed for
1.65v-3.6v, 16-bit Dual Supply Level ShiftingBidirec-
tional Transceiver with 3 state outputs operation.
Contains two separate supply rails: B port (VCCB)
must set higher voltage (equal) then A port
(VCCA).This arrangement permits translation from a
1.8-2.5V to 3.3V environment.
The
PO74G164245A
features independent 16-bit
Bidirectional Transceiver with 3 state outputs. Each
output is disabled when the associated output-
enable(OE) input is high.
