2.5V 16-Bit Bidirectional Transceiver
with 3-State Outputs
Product Features
Product Description
• PI74AVC+16245 is designed for low-voltage operation,
VCC = 1.65V to 3.6V
Pericom Semiconductor’s PI74AVC+ series of logic circuits are
produced using the Company’s advanced submicron CMOS
technology, achieving industry leading speed.
• True ±24mA Balanced Drive @ 3.3V
The PI74AVC+16245 is a 16-bit bidirectional transceiver designed
for asynchronous two-way communication between data buses.
The direction control input pin (xDIR) determines the direction of
data flow through the bidirectional transceiver. The Direction and
Output Enable controls are designed to operate this device as either
two independent 8-bit transceivers or one 16-bit transceiver. The
output enable (OE) input, when HIGH, disables both A and B ports
by placing them in HIGH Z condition.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the
minimum value of the resistor is determined by the current sinking
ability of the driver.
• Compatible with Philips and T.I. AVC Logic family
• IOFF supports partial power-down operation
• 3.6V I/O Tolerant inputs and outputs
• All outputs contain a patented DDC
(Dynamic Drive Control) circuit that reduces noise
without degrading propagation delay
• Industrial operation: –40°C to +85°C
• Available Packages:
– 48-pin 240-mil wide plastic TSSOP
– 48-pin 173-mil wide plastic TVSOP

Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested.)
Notes:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may
affect reliability.

D. The outputs are measured one at a time with one transition per measurement.
E. tPLZ and tPHZ are the same as tdis
F. tPZL and tPZH are the same as ten
G. tPLH and tPHL are the same as tpd
