The 74LVT245WM is a low voltage octal non-inverting Bidirectional Transceiver with 3-state inputs/outputs and is intended for bus-oriented applications. The transmit/receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active-HIGH) enables data from A ports to B ports, receive (active-LOW) enables data from B ports to A ports. The output enables input, when HIGH disables both A and B ports by placing them in a HIGH Z condition. This transceiver is designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT245 is fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
Input and output interface capability to systems at 5V VCC
Live insertion/extraction permitted
Power up/down high impedance provides glitch-free bus loading
