74AC245MTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC245MTC is an octal bidirectional transceiver featuring three-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 2 V to 6 V and supports a maximum propagation delay of 8.5 ns. The device provides high drive capability with 24 mA low-level output current and -24 mA high-level output current at both A and B ports. It utilizes CMOS input and output levels and functions as a non-inverting buffer. The component is housed in a TSSOP-20 surface-mount package and is rated for operation between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the data direction controlled?

Direction is determined by the Transmit/Receive (T/R) input; a high level enables data flow from A to B, while a low level enables flow from B to A.

What happens when the Output Enable input is high?

When the Output Enable input is high, both A and B ports are disabled and placed in a high-impedance state.
