74ABT2240N,112

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74ABT2240N,112 is an octal inverting buffer utilizing high-performance BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +85 °C. The device features two output enable inputs controlling three-state outputs, each incorporating 30 Ω series resistance for internal termination. Propagation delays are specified with maximum values of 4.9 ns (tPLH) and 6.0 ns (tPHL) at the extended temperature limit. Input capacitance is 3 pF, and output capacitance is 7 pF.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus interface with integrated 30 Ω series termination resistors in both HIGH and LOW states
• Dual output enable inputs allowing independent control of four three-state outputs each
• Supports live insertion and extraction operations without system disruption
• Power-up state defaults to three-state high-impedance condition

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers requiring controlled signal impedance
• Clock distribution networks needing reduced line noise
• Bus receiver and transmitter interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' against current manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure design margins account for the full operating temperature range and supply voltage variations defined in the recommended operating conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require octal buffering with built-in series termination to eliminate external resistors. The ABT logic family provides a balance of speed and power dissipation suitable for 5 V applications. Verify that the DIP-20 package format meets the mechanical constraints of the target PCB layout and assembly process.
