The SN74LVC543APWT is a high-performance, octal transparent D-type latch with 3-state outputs from Texas Instruments. Designed with the advanced LVC (Low-Voltage CMOS) technology, this integrated circuit (IC) is optimized for operation at 2.7V to 3.6V, making it suitable for interfacing with 3.3V logic levels while providing 5V tolerant inputs.
This device features eight latches with 3-state outputs for bus-oriented applications. The latches appear transparent to data when the latch-enable (LE) input is high. When LE is low, the data that meets the setup time is latched. Data appears on the outputs when the output-enable (OE) input is low. If OE is high, the outputs are in the high-impedance state, which is crucial for bus-driving applications where multiple devices may share a common bus line.
The SN74LVC543APWT is designed to offer a robust set of features such as:
- High Drive: Capable of driving 24mA at the outputs, ensuring strong signal transmission over long traces or to multiple devices.
- Low Power Consumption: The LVC technology provides a significant reduction in power consumption compared to traditional CMOS circuits, without sacrificing speed.
- Wide Operating Temperature Range: This device is functional over a broad temperature range from -40°C to 85°C, accommodating various environmental conditions.
- Compatibility: Inputs are compatible with 5V systems, allowing for easy integration into mixed-voltage environments.
With its small-footprint TSSOP (Thin Shrink Small Outline Package), the SN74LVC543APWT is ideal for space-constrained applications. The package is designed for surface-mount technology, contributing to a more compact and reliable PCB design.
Whether you're designing high-speed data acquisition systems, telecommunications interfaces, or need a reliable bus driver for your microcontroller-based projects, the SN74LVC543APWT from Texas Instruments offers a combination of performance, power efficiency, and versatility that can meet a wide range of design requirements.
