1-Bit to 4-Bit Address/Driver
with 3-State Outputs
Product Features
• PI74ALVCH16344 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
www.DataS•heTeyt4pUic.caolmVOHV (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
• Packages available:
56-pin 240 mil wide plastic TSSOP (A)
56-pin 300 mil wide plastic SSOP (V)
Product Description
Pericom Semiconductor’s PI74ALVCH series of logic circuits are
produced in the Company’s advanced 0.5 micron CMOS technology,
achieving industry leading speed.
The PI74ALVCH16344 is a 1-bit to 4-bit buffer/driver designed for
2.3V to 3.6V Vcc operation.
The address/driver is designed for applications where four seperate
memory locations must be addressed by a single address.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor; the minimum
value of the resistor is determined by the current-sinking capability
of the driver.
The PI74ALVCH16344 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.
