Overview
The 74ALVC164245PVG8 is a 16-bit dual-supply bus transceiver manufactured by Renesas Electronics. It operates with VCCA ranging from 3V to 3.6V and VCCB from 3V to 5.5V, enabling translation between different voltage domains. The device features a propagation delay of 4.2 ns and functions within an operating temperature range of -40°C to +85°C. Packaged in SSOP-48, it supports surface-mount installation and includes three-state outputs for effective bus management.
Feature Summary
- Provides bidirectional data transmission between two distinct power supply domains
- Supports simultaneous operation as one 16-bit or two 8-bit transceivers
- Maintains high impedance state when either supply voltage is zero
Applications
- Voltage level conversion between 3.3V and 5V systems
- Bidirectional bus driving applications
- Mixed-voltage system interconnects
Procurement Notes
Verify the package designation carefully, as the suffix 'PVG' typically indicates SSOP-48 while 'PAG8' denotes TSSOP-48. Confirm that the specific variant matches the required pin count and channel configuration. Ensure compatibility with the target voltage levels before integration into the design.
Selection Notes
Select this component when interfacing logic families requiring different supply voltages. The ALVC series offers performance superior to standard CMOS TTL. Verify that the required channel width and package type align with the PCB layout constraints and thermal requirements of the application.
Part Context
This part belongs to the 74ALVC164245 family of 16-bit bus transceivers. It is designed for low-voltage applications and provides high-speed data transfer capabilities. The device is suitable for mixed-signal environments where reliable signal integrity across different voltage domains is critical.
Replacement Considerations
The 74ALVC164245XTS48G/TR is a listed alternative offering similar functionality in a TSSOP-48 package. Verify pinout compatibility and electrical specifications before substitution.
