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.
