Texas Instruments Logic - Buffers, Drivers, Receivers, Transceivers SN74HCT540DWR

The SN74HCT540DWR is an octal buffer and line driver with 3-state outputs, designed to operate within a voltage range of 4.5 V to 5.5 V. It features low power consumption, with a maximum supply current of 80 ¬µA, and a typical propagation delay of 12 ns at 5 V. The device can drive up to 15 LSTTL loads and is TTL-compatible, making it suitable for interfacing with various digital systems. The buffer provides inverted data at the outputs and includes a 2-input NOR gate for output enable control, allowing all outputs to enter a high-impedance state when either output-enable input is high. The device is available in a 20-pin SOIC package, with an operating temperature range of -40¬8C to 85¬8C. It is important to tie the output enable pins to VCC through a pull-up resistor to ensure proper operation during power transitions. This product is ideal for applications requiring reliable signal buffering and driving capabilities in digital circuits.
