Working Principle of 74ALVCH245WM

The 74ALVCH245WM works on the principle of high-speed differential signalling. It offers both single-ended and differential signals in full-duplex mode with up to 20 cm cable length. The driver signals are provided with 20 mV of differential swing. The transceiver features thermal-shutdown protection with hysteresis that protects against high-temperature failures.

The device features variable delay select pins that allow the user to adjust the delays of both the receive and transmit paths. The transmit path has selectable output slew-rate control, allowing the user to match the output frequencies to the application.

The 74ALVCH245WM includes an input/output buffer section with two data bits, a receiver/transmitter output, an enable/disable input, a forward/backward data flow control input, and an output enable/disable input. The 74ALVCH245WM provides additional features such as glitch-free operation and data rate auto-direction sensing. It also features a separate VCC supply pin that can also be used in lieu of the Vcc/LED pin to reduce power consumption in low-power applications.
