产品描述

These devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (G)\ input is at a high logic level.

To ensure the high-impedance state during power up or power down, G\ 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.

产品特性

4.5-V to 5.5-V VCC Operation
Wide Operating Temperature Range of –55°C to 125°C
Balanced Propagation Delays and Transition Times
Standard Outputs Drive Up To 10 LS-TTL Loads
Significant Power Reduction Compared to LS-TTL Logic ICs
Inputs Are TTL-Voltage Compatible
