SN74ALVC164245DL

Translators, Level Shifters Overview

The SN74ALVC164245DL is a 16-bit non-inverting bus transceiver from the Texas Instruments ALVC logic series. It features dual power supply rails, with Port A operating at 2.3 V to 3.3 V and Port B at 3.3 V to 5.5 V. The device provides bidirectional data transfer with three-state outputs. Key electrical parameters include a maximum propagation delay of 5.8 ns at 5 V and output drive currents of ±24 mA. It operates within a temperature range of -40 °C to +85 °C and is housed in a 48-pin SSOP package.

Translators, Level Shifters Feature Summary

• Supports voltage translation between 2.5 V/3.3 V and 3.3 V/5.5 V domains via independent power rails
• Provides bidirectional data transmission with three-state outputs for bus line isolation
• Features high-speed performance with low propagation delay characteristics
• Includes robust latch-up protection exceeding 250 mA per JESD 17 standards

Translators, Level Shifters Applications

• Level shifting interfaces in electronic point-of-sale (EPOS) systems
• Peripheral equipment connections requiring mixed-voltage compatibility
• Motor driver interface circuits
• Wireless and telecommunications infrastructure components

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-48 tube packaging configuration when sourcing. Confirm that the target application requires the specific voltage ranges supported by the ALVC series rather than lower-voltage alternatives like AVCBH. Ensure ESD handling protocols are followed during assembly due to the CMOS technology used in this logic family.

Translators, Level Shifters Selection Notes

Select this component when interfacing between 3.3 V logic devices and 5 V legacy systems or 2.5 V low-power environments. The dual-supply architecture allows flexible level shifting without external resistors. Consider the SSOP package constraints for PCB layout density. Verify that the required data rate does not exceed the capabilities of the ALVC series compared to faster AVCBH options.

Translators, Level Shifters Part Context

This part belongs to the Texas Instruments SN74ALVC164245 family of widebus transceivers. It is designed for high-density applications requiring multiple channels of simultaneous data transfer.
