Product Information

Features

Operating Voltage Range of 4.5 V to 5.5 V
High-Current Outputs Drive Up To 15 LSTTL Loads
Low Power Consumption, 80-µA Max I_CC
Typical t_pd = 12 ns
±6-mA Output Drive at 5 V
Low Input Current of 1 µA Max
Inputs Are TTL-Voltage Compatible
High-Current 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers

Description

These bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\ input is high.

To ensure the high-impedance state during power up or power down, OE\ should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
