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.
