  • Operating Voltage Range of 4.5 V to 5.5 V
  • High-Current 3-State Outputs Interface Directly With System Bus or Can Drive Up To 15 LSTTL Loads
  • Low Power Consumption, 80-µA Max ICC
  • Typical tpd = 12 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
  • Inputs Are TTL-Voltage Compatible
  • Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs)


These octal buffers and line drivers are designed to have the performance of the popular ’HC240 series devices and to offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout.

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 ’HCT541 devices provide true data at the outputs.
