SN74F245DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F245DBR is an octal bus transceiver manufactured by Texas Instruments, belonging to the SN74F logic series. It features a 20-pin SOIC package and supports tri-state outputs for bidirectional data transmission. The device operates within a supply voltage range of 4.5 V to 5.5 V and maintains TTL input and output levels. Key electrical specifications include a propagation delay of 7 ns, a low-level output current of 64 mA, and a high-level output current of -15 mA. It functions as a non-inverting transceiver with eight channels.
