SN74LVC244APWT

SN74LVC244APWT Description

The SN74LVC244APWT from Texas Instruments is a high-performance, dual 4-bit non-inverting buffer/driver designed for 1.65V to 3.6V voltage operation. Packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package) with tape-and-reel (TR) delivery, this IC is optimized for surface-mount applications requiring robust signal integrity and low-power consumption. As part of the 74LVC series, it combines 24mA output drive strength (both high and low) with a wide operating voltage range, making it ideal for interfacing between mixed-voltage systems. The device is RoHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited shelf life), ensuring reliability in industrial and consumer electronics.

SN74LVC244APWT Features

• Dual 4-bit buffers: Two independent buffer banks (2 elements × 4 bits each) for flexible signal distribution.
• Wide voltage range (1.65V–3.6V): Supports low-voltage logic levels (e.g., 1.8V, 2.5V, 3.3V) with 5V-tolerant inputs for backward compatibility.
• High drive capability: 24mA sink/source current per channel, enabling strong fan-out in bus-heavy designs.
• Low power consumption: CMOS technology minimizes static power dissipation.
• Robust packaging: 20-TSSOP ensures compact PCB footprint and thermal efficiency.
• Enhanced ESD protection: Exceeds JESD 22 standards for electrostatic discharge resilience.

SN74LVC244APWT Applications

• Voltage-level translation: Bridges 1.8V/3.3V logic in mixed-voltage systems (e.g., microcontrollers to peripherals).
• Bus buffering/isolation: Ideal for memory interfaces, address/data buses, and I²C/SPI signal conditioning.
• Industrial automation: Used in PLCs, motor controllers, and sensor interfaces due to noise immunity.
• Consumer electronics: Signal integrity in smartphones, tablets, and IoT devices.
• Automotive systems: Supports infotainment and control modules (non-safety-critical).
