74LVC2245ADB,118

Overview

The 74LVC2245ADB,118 is an octal bus transceiver manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.2 V to 3.6 V and features three-state outputs. The device provides non-inverting data transmission across eight channels with a maximum propagation delay of 3.6 ns. It supports LVTTL input and output levels and offers low-level and high-level output currents of 24 mA each. The component is housed in a 24-pin SSOP package and functions reliably within an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Provides bidirectional data transfer between two buses using eight independent channels
• Supports voltage translation between different logic families via separate A and B side supplies
• Features three-state outputs to isolate the bus during inactive states

Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the specific suffix 'ADB' corresponds to the SSOP-24 package variant when sourcing. Confirm RoHS compliance status through official Nexperia documentation prior to integration. Ensure the design accommodates the specified 1.2 V to 3.6 V supply range for both sides of the transceiver to maintain signal integrity.

Selection Notes

Select this component for designs requiring voltage level shifting between 1.2 V and 3.6 V domains. The SSOP-24 package is suitable for applications needing moderate pin density. Consider the 3.6 ns propagation delay for timing-critical paths. Verify that the 24 mA drive current meets the load requirements of the destination circuitry.

Part Context

This part belongs to the 74LVC family of CMOS logic devices from Nexperia. It serves as a successor or alternative to older 74FCT and 74ACT series transceivers, offering lower power consumption and wider voltage compatibility. The 74LVC2245 variant specifically includes auto-direction sensing capabilities, distinguishing it from the standard 74LVC245.
