Octal Buffers And Line Drivers With 3-State Outputs - SN74HC540
Datasheet
 

Description

These octal buffers and line drivers feature the performance of the popular ’HC240 series and 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 ’HC540 devices provide inverted data at the outputs.

Features

  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads
  • Low Power Consumption, 80-µA Max ICC
  • Typical tpdd = 8 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
  • Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs)
