Description
Pericom Semiconductor’s PI74ALVCH16244 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 PI74ALVCH16244 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.
Features
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
Bus Hold retains last active bus state during 3-State,
eliminating the need for external pullup resistors
Industrial operation at –40°C to +85°C
Packaging:
– 48-pin 240-mil wide plastic TSSOP (A)
