1 / 19 page SN54HC540, SN74HC540 OCTAL BUFFERS AND LINE DRIVERS WITH 3STATE OUTPUTS SCLS007D − MARCH 1984 − REVISED AUGUST 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Wide Operating Voltage Range of 2 V to 6 V D High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 8 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs) description/ordering information 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.
