PI74ALVCH16344
Overview
- 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
- 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.
