CALVC164245IDLREP

Translators, Level Shifters Overview

The CALVC164245IDLREP is a military-enhanced, bidirectional voltage-level translating transceiver from Texas Instruments. It integrates two independent circuits, each providing eight channels for 16-bit data transmission. The device supports dual power supply rails: VCCA operates between 2.3V and 3.6V, while VCCB ranges from 3V to 5.5V. This configuration enables seamless translation between 2.5V/3.3V and 3.3V/5V logic environments. Housed in a 48-SSOP package, it features three-state outputs and non-inverting polarity. The component is designed for high reliability with an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Military-grade enhanced reliability suitable for demanding operational environments
• Bidirectional voltage level translation between distinct low-voltage and standard logic domains
• Dual independent power supply architecture allowing flexible interface configurations

Translators, Level Shifters Applications

• Military and aerospace electronic systems requiring robust signal integrity
• Industrial control interfaces connecting disparate voltage logic levels
• Telecommunications infrastructure equipment needing reliable data translation

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'REP' indicates the required military or enhanced grade qualification during procurement. Confirm that the 48-SSOP package dimensions align with the target PCB footprint. Ensure the design accommodates the specified dual voltage rail requirements for both VCCA and VCCB pins to function correctly within the stated operational limits.

Translators, Level Shifters Selection Notes

Select this component when military-grade reliability is mandatory for voltage translation tasks. It is appropriate for designs requiring simultaneous interfacing between 2.5V/3.3V and 3.3V/5V domains. Consider the 48-SSOP package constraints and the need for separate power supplies for A and B ports when integrating into the system architecture.

Translators, Level Shifters Part Context

This part belongs to the SN74ALVC164245 family of widebus transceivers. The 'CALVC' prefix typically denotes a specific enhanced or qualified variant of the standard ALVC series. It serves as a bridge for high-density digital interfaces where voltage mismatch between subsystems must be resolved without signal inversion.

Translators, Level Shifters Replacement Considerations

Standard commercial variants like SN74ALVC164245DLR lack the enhanced qualification. Verify if the military specification is strictly required; otherwise, commercial equivalents may suffice.
