PI74ALVCH162244
16-Bit Buffer Driver
with 3-State Outputs
Product Features
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.
• PI74ALVCH162244 is designed for low-voltage operation
• V = 2.3V to 3.6V
CC
• Hysteresis on all inputs
The PI74ALVCH162244 is an non-inverting 16-bit buffer/driver
• Typical V
(Output Ground Bounce)
OLP
designed for low voltage 2.3V to 3.6V V operation.
CC
< 0.8V at V = 3.3V, T = 25°C
CC
A
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.
• Typical V
(Output V
Undershoot)
OH
OHV
< 2.0V at V = 3.3V, T = 25°C
CC
A
• Output ports have equivalent 26-Ohm series resistors:
no external resistors are required
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.
• 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:
To ensure the high-impedance state during power up or power
down, OE should be tied to V through a pullup resistor in which
CC
the minimum value is determined by the current-sinking capability
of the driver.
– 48-pin 240 mil wide plastic TSSOP (A)
– 48-pin 300 mil wide plastic SSOP (V)
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.
