74F245SJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F245SJ is an octal bidirectional transceiver with 3-STATE outputs, manufactured by Fairchild Semiconductor. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. The device features non-inverting buffers with asymmetric current sinking capabilities: 24mA at the A ports and 64mA at the B ports. Propagation delay ranges from 2.0ns to 7.5ns depending on temperature conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting bidirectional buffers for bus-oriented applications
• Features 3-STATE outputs that enter a high impedance state when disabled
• Asymmetric drive strength allows higher current sinking capability on side B compared to side A
