16-Bit Buffer Driver
with 3-State Outputs
Product Features
PI74ALVCH162244 is designed for low-voltage operation
VCC = 2.3V to 3.6V
Hysteresis on all inputs
Typical VOLP (Output Ground Bounce)
< 0.8V at VCC = 3.3V, TA = 25°C
Typical VOHV (Output VOH Undershoot)
< 2.0V at VCC = 3.3V, TA = 25°C
Output ports have equivalent 26-Ohm series resistors:
no external resistors are required
Bus Hold retains last active bus state during 3-State,
eliminating the need for external pullup resistors
Industrial operation: –40°C to +85°C
Packages available:
– 48-pin 240 mil wide plastic TSSOP (A)
– 48-pin 300 mil wide plastic SSOP (V)
Logic Block Diagram
Product Description
Pericom Semiconductor’s PI74ALVCH series of logic circuits
are produced using the Company’s advanced 0.5 micron CMOS
technology, achieving industry leading speed.
The PI74ALVCH162244 is an non-inverting 16-bit buffer/driver
designed for low voltage 2.3V to 3.6V VCC operation.
The buffer/driver is designed specifically to improve both the
performance and density of 3-State memory address drivers, clock
drivers, and bus-oriented receivers and transmitters.
The device can be used as four 4-bit buffers, two 8-bit buffers, or
one 16-bit buffer. It provides non-inverting outputs and symmetri-
cal active-low output-enable (OE) inputs.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pullup resistor in which
the minimum value is determined by the current-sinking capability
of the driver.
The PI74ALVCH162244 has “Bus Hold” which retains the data
input’s last state whenever the data input goes to high-impedance
preventing “floating” inputs and eliminating the need for pullup/
down resistors.
