The SN74HCT540DWR from Texas Instruments is an octal buffer and line driver designed with 3-state outputs. This component facilitates efficient printed circuit board layout due to its data flow-through pinout, where all inputs are on the opposite side from the outputs.
Key electrical characteristics include an operating voltage range of 4.5 V to 5.5 V, low power consumption with a maximum ICC of 80 µA, and a typical propagation delay of 12 ns. The device offers ±6 mA output drive at 5 V and low input current of 1 µA maximum. Its inputs are TTL-voltage compatible, and the high-current 3-state outputs can interface directly with a system bus or drive up to 15 LSTTL loads.
The 3-state control gate is a 2-input NOR. When either output-enable (OE1 or OE2) input is high, all eight outputs enter a high-impedance state. The SN74HCT540 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 pull-up resistor.
This device is available in a 20-SOIC surface mount package. The operating temperature range is -40°C to 85°C (TA).
