74LVC16245APVG

Overview

The 74LVC16245APVG is a 16-bit bus transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 1.65 V to 3.6 V and features 3-state outputs. The device supports TTL/CMOS input levels and LVTTTL output levels, with a propagation delay of 4 ns. It is housed in a TSSOP-48 package and functions across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides bidirectional data transmission for 16-bit buses with three-state output capability
• Supports mixed-voltage environments allowing translation between 3.3 V and 5 V logic systems
• Includes I_OFF circuitry to prevent damaging backflow current during partial power-down states

Applications

• Mixed 3.3 V and 5 V memory mapping applications
• Clock drivers and buffer circuits
• Bidirectional bus architectures requiring level shifting

Procurement Notes

Verify the manufacturer designation on the component marking, as this part number may be sourced from IDT or Nexperia under similar naming conventions. Confirm the specific suffix 'PVG' corresponds to the required tape-and-reel packaging format. Ensure the order matches the exact voltage and temperature specifications required for your design environment.

Selection Notes

Select this component when designing systems that require robust 16-bit data transfer between different voltage domains. It is suitable for applications needing high-speed signal integrity with low power consumption. Consider the TSSOP-48 package constraints for PCB layout and ensure thermal management aligns with the specified industrial temperature range.

Part Context

This device belongs to the LVC logic family, designed for low-voltage CMOS applications. It serves as a standard interface solution for connecting microprocessors, memory devices, and other digital components operating at varying logic levels within embedded systems.

Replacement Considerations

The 74LVC16245ADGGRG4 from Texas Instruments offers compatible electrical characteristics and pinout. Verify package dimensions and specific suffix requirements before substitution.
