74ABT245DB,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT245DB,118 is an octal bidirectional bus transceiver manufactured by Nexperia USA Inc. It features BiCMOS technology for high-speed operation and direct interface with TTL levels. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides an output capability of +64 mA in the low state and -32 mA in the high state. Propagation delays are specified between 1.0 ns and 4.6 ns at 5.0 V. The component is housed in a 20-lead SO plastic small outline package (SOT163-1) and is fully specified for partial power-down applications using IOFF circuitry.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package type, as the 74ABT245 family includes both SO20 and TSSOP20 variants. Confirm the temperature range specification aligns with the application environment requirements. Ensure compatibility with the system's logic voltage levels before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with high drive strength and fast switching speeds is required. The BiCMOS technology offers superior performance compared to standard CMOS options. Consider the specific package dimensions if PCB space is constrained, noting the distinction between the SO20 and TSSOP20 versions available in the product line.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of octal transceivers from Nexperia. The 'D' in the model number indicates the SO20 package variant, distinguishing it from the PW suffix which denotes the TSSOP20 package. The series is designed for applications requiring robust signal integrity and high current drive capabilities in 5V logic environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for alternative octal transceivers with similar drive currents and propagation delays. Verify pinout compatibility and package dimensions before substituting. Ensure the replacement supports the required IOFF functionality if partial power-down operation is necessary for the design.
