Product Description
Pericom Semiconductor’s PI74LVC series of logic circuits are
produced using the Company’s advanced submicron CMOS tech-
nology, achieving industry leading speed.
The PI74LVCC4245A is a non-inverting 8-bit Bidirectional Trans-
ceiver that uses two separate power supply rails. A-port (V
set to operate at 5V and B-port (V
5V. This allows for translation from a 3.3V to a 5Venvironment and
vice-versa. This tranceiver is designed for asynchronous two-way
communication between data buses. The direction control input pin
(DIR) determines the dataflow from the A bus to the B bus or from
the B bus to the A bus. The output enable (OE) input, when HIGH,
disables both A and B ports by placing them in HIGH Z condi-
tion.
