Overview
The Nexperia 74ALVC164245DGG-QJ is a 16-bit dual supply translating transceiver with 3-state outputs, housed in a 48-pin TSSOP package. It operates within a VCC(A) range of 1.5 V to 3.6 V and a VCC(B) range of 1.5 V to 5.5 V. The device provides non-inverting data flow between ports with propagation delays as low as 1.0 ns. It supports partial power-down via IOFF circuitry and withstands ESD protection exceeding 2000 V (HBM).
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 standards.
- Dual supply architecture enabling translation between 3 V and 5 V buses.
- IOFF circuitry prevents backflow current during partial power-down mode.
- High-impedance outputs maintained when either supply voltage is zero.
Applications
- Mixed 3 V and 5 V supply environments.
- Engine control units.
- Body control modules.
- Transmission control units.
- Electronic instrument clusters.
Procurement Notes
Verify the specific suffix 'QJ' corresponds to the automotive-grade 74ALVC164245-Q100 variant. Confirm the package type matches the 48-lead TSSOP (SOT362-1) specification. Ensure the required operating temperature range aligns with the -40 °C to +125 °C rating defined for this component.
Selection Notes
Select this component for applications requiring bidirectional level shifting between distinct voltage domains. The dual octal configuration allows independent direction control for each 8-bit segment. Verify that the input transition rates remain within the specified limits to maintain signal integrity across the mixed-voltage interface.
Part Context
This part belongs to the Nexperia ALVC logic family, designed for high-performance CMOS applications. It serves as a bridge between different logic families, specifically facilitating communication between 3 V and 5 V systems while maintaining compatibility with TTL levels.
Replacement Considerations
The SN74AVCH16T245GQLR is listed as an obsolete alternative. Designers should verify pinout compatibility and electrical specifications before substituting other 16-bit translators.
