1 / 14 page SN54HCT540, SN74HCT540 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS SCLS008C – MARCH 1984 – REVISED MARCH 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Voltage Range of 4.5 V to 5.5 V D Low Power Consumption, 80-µA Max ICC D Typical tpd = 12 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Inputs Are TTL-Voltage Compatible D High-Current 3-State Outputs Interface Directly With System Bus or Can Drive Up To 15 LSTTL Loads D Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs) description/ordering information These octal buffers and line drivers are designed to have the performance of the ’HCT240 devices and 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 ’HCT540 devices provide inverted data at the outputs. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
