Widebus Family Operates From 1.65 V to 3.6 V Max tpd of 4.4 ns at 3.3 V ±12 mA Output Drive at 3.3 V Output Ports Have Equivalent 26- Series Resistors, So No External Resistors Are Required Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors Latch-Up Performance Exceeds 250 mA Per JESD 17
description/ordering information
This 1-bit to 4-bit address driver is designed for 1.65-V to 3.6-V VCC operation. The SN74ALVCH162344 is used in applications in which four separate memory locations must be addressed by a single address. The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, the output enable (OE) inputs 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. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. ORDERING INFORMATION
