Overview
The STMicroelectronics 74LCX162541TTR is a low voltage CMOS 16-bit bus buffer featuring non-inverted logic and three-state outputs. It operates within a supply voltage range of 2.0V to 3.6V, with data retention support at 1.5V. The device incorporates 5V tolerant inputs and outputs, allowing safe interfacing with 5V signal environments. It includes internal 26Ω series resistors in the output paths to reduce line noise during high-speed operation. Propagation delay is specified as a maximum of 4.4ns at VCC = 3V.
Feature Summary
- Features 5V tolerant inputs and outputs for direct interfacing with 5V signal environments.
- Includes integrated 26Ω series resistors in the output lines to minimize line noise in high-speed applications.
- Provides power-down protection on both inputs and outputs to prevent excessive current draw during low-power states.
Applications
- Used as a memory address driver in 3-state memory systems.
- Interfaces between 3.3V logic circuits and 5V signal environments.
- Functions as a high-speed bus buffer for low power applications.
Procurement Notes
Verify that the specific order code matches the TSSOP-48 package configuration required for your design. Confirm that the operating voltage requirements align with the 2.0V to 3.6V specification range. Ensure that the 5V tolerance capability meets the interface requirements of your target system components.
Selection Notes
Select this component when a 16-bit wide bus buffer is required for 3.3V logic systems interfacing with 5V signals. The inclusion of series resistors makes it suitable for high-speed applications where line noise reduction is critical. Verify that the TSSOP-48 package fits the available board space and thermal constraints.
Part Context
This device belongs to the 74LCX family of low voltage CMOS logic devices manufactured by STMicroelectronics. It is functionally compatible with the standard 74 series 162541 but optimized for lower voltage operation. The TTR suffix indicates the device is supplied in a tape and reel format suitable for automated surface-mount assembly processes.
Replacement Considerations
The datasheet notes pin and function compatibility with the 74 series 162541. Designers should verify that any substitute part maintains the same 5V tolerance specifications and propagation delay characteristics to ensure circuit integrity.
