74ABT245CSJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT245CSJX is an octal bidirectional transceiver with 3-STATE outputs, manufactured using high-performance BiCMOS technology. It operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of -40°C to +85°C. The device features eight non-inverting buffers with A and B ports capable of sinking 64 mA and sourcing 32 mA. Propagation delays are specified at 1.0 ns minimum and 3.6 ns maximum under standard conditions (CL = 50 pF). It includes latch-up protection exceeding 500 mA per JEDEC Std 17 and ESD protection exceeding 2000 V per MIL STD 833 Method 3015.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation M20D corresponds to the required 20-Lead Small Outline Package (SOP) configuration. Confirm that the 'X' suffix indicates tape and reel packaging availability if automated assembly is required. Ensure compatibility with existing board layouts regarding pinout and thermal dissipation requirements for the SOP form factor.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed bidirectional data transfer with significant current drive capabilities. The ABT series offers superior speed compared to standard TTL or CMOS alternatives while maintaining low static power dissipation. Consider the guaranteed output skew specifications when designing multi-bit buses where timing alignment between parallel signals is critical for system stability.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, which utilizes BiCMOS technology to achieve performance levels between standard 74AS and 74ALS families. The 74ABT245 variant specifically provides octal buffering functionality. The CSJX designation identifies the specific manufacturer part number including the package type and packaging style, distinguishing it from other variants like the CJC or CPC packages.
