74AVCH1T45W6-7

Overview

The 74AVCH1T45W6-7 is a single-channel dual-supply voltage level translator from Diodes Incorporated, belonging to the AVCH logic series. It operates within a supply voltage range of 1.2 V to 3.6 V and features a propagation delay of 5.6 ns. The device utilizes a SOT-26-6 surface-mount package and supports 3-state outputs with bus hold functionality. Designed for low-power applications, it draws a working supply current of 20 uA and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Provides bidirectional voltage translation between two independent power domains
• Integrates bus hold circuitry to maintain stable logic states during input transitions
• Supports 3-state output configuration for efficient bus line management

Applications

• Interfacing low-voltage microcontrollers with higher-voltage peripheral devices
• Connecting memory modules operating at different voltage levels
• Facilitating communication between mixed-signal system components

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm that the received units match the specified SOT-26-6 packaging and AVCH series designation. Ensure storage conditions comply with manufacturer guidelines to preserve solderability and electrical integrity prior to assembly.

Selection Notes

Select this component when designing systems requiring precise voltage shifting between 1.2 V and 3.6 V domains. The single-channel architecture suits space-constrained layouts needing minimal footprint. Consider the 5.6 ns delay for timing-critical paths and verify thermal requirements against the -40°C to +85°C operational range.

Part Context

This part belongs to the 74AVCH family of advanced CMOS logic devices optimized for high-speed voltage translation. It complements other translators in the series by offering a compact solution for single-bit data transfer. The AVCH series emphasizes low power consumption while maintaining signal integrity across varying supply voltages.

Replacement Considerations

Cross-reference with equivalent single-channel voltage translators from Diodes Incorporated featuring similar voltage ranges and package dimensions. Verify pin compatibility and logical function equivalence before substitution.
