Overview
The SN74LVTH18502APMR is an 18-bit universal bus transceiver from the Texas Instruments SCOPE family, designed for low-voltage applications. It operates within a supply voltage range of 2.7V to 3.6V and supports data transmission across 18 bits simultaneously. The device utilizes a 64-LQFP package with dimensions of 10x10 mm, suitable for surface-mount technology. It functions as an ABT scan test equipment component, ensuring reliable signal integrity in digital logic circuits.
Feature Summary
- Supports 18-bit universal bus data transmission
- Operates at low voltage levels between 2.7V and 3.6V
- Designed for use in ABT scan test equipment applications
Applications
- ABT scan test equipment
- Universal bus transceivers
- Low-voltage digital logic circuits
Procurement Notes
Verify the specific suffix 'APMR' indicates the tape-and-reel packaging format rather than tray packaging. Confirm the operating temperature range aligns with system requirements, typically spanning -40°C to +85°C. Ensure compatibility with the 2.7V to 3.6V power supply specifications before integration into the design.
Selection Notes
Select this component when an 18-bit wide bus interface is required within low-voltage constraints. The LQFP-64 package offers a compact footprint for high-density PCB layouts. Consider the ABT logic family characteristics for appropriate switching speeds and drive capabilities in scan test environments.
Part Context
This part belongs to the SN74LVTH18502A series, which includes variants like the SN74LVTH18502APM. The 'R' suffix specifically denotes reel packaging, distinguishing it from tray-packaged counterparts. It shares functional similarities with other SCOPE family devices but is optimized for specific low-voltage bus applications.
Replacement Considerations
The SN74LVTH18502APM serves as a direct pin-compatible alternative, differing primarily in packaging type (tray vs. reel). Ensure that any substitute maintains the same 18-bit width and 2.7V-3.6V operating voltage range to guarantee functional equivalence in the circuit.
