U74HCT541
OCTAL BUFFERS AND LINE
DRIVERS WITH 3-STATE
OUTPUTS
„ DESCRIPTION
The U74HCT541 is octal buffers and line drivers are with
3-state outputs and 8 channels.
The 3-state control gate is a 2-input NOR. If either
output-enable( OE1 or OE2 )input is high,all eight outputs are in
the high-impedance state.The ‘UCTHCT541’ devices provide true
data at the outputs.
„ FEATURES
* Operating Voltage Range of 4.5V to 5.5V
* High-Current 3-State Outputs Interface Directly With System
Bus or Can Drive Up To 15 LSTTL Loads
* Low Power Consumption ICC: 4μA (Max.)
* Typical tpd=12ns
* ±6mA Output Drive at 5V
* Low Input Current of 1uA max`
* Inputs Are TTL-Voltage Compatible
* Data Flow-Through Pinout(All Inputs on Opposite Side From
Outputs)
