Product Overview: SN74ABT8543DL from Texas Instruments

The SN74ABT8543DL is a high-performance integrated circuit from Texas Instruments, designed to meet the rigorous demands of modern digital systems. This device is part of the ABT family, which stands for Advanced BiCMOS Technology, indicating that it combines the high speed of bipolar with the low power of CMOS to deliver exceptional performance.

This product is a 10-bit transparent D-type latch with 3-state outputs, making it an ideal component for temporary storage of data. It can be used to hold intermediate values or to provide a hold time to allow for the settling of signals, which is particularly useful in systems where data integrity and timing are critical.

Key Features

• Logic Type: D-Type Latch
• Number of Bits per Element: 10
• Output Type: 3-State
• Operating Temperature: -40°C to 85°C, making it suitable for industrial applications
• Package / Case: 48-BSSOP (Shrink Small Outline Package)
• Mounting Type: Surface Mount
• Supply Voltage: 4.5V to 5.5V, compatible with 5V systems
• High-Speed Performance: Typically 3.6 ns maximum propagation delay time

The SN74ABT8543DL is designed to be used in a wide range of applications, from data processing and telecommunications to industrial control systems. Its transparent operation means that when the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

Additionally, this device features a bus-hold circuitry on its inputs, which eliminates the need for external pull-up or pull-down resistors and ensures that the inputs remain at a valid logic level even when they are not actively being driven.

For designers and engineers looking for a reliable and high-performance solution for data storage and signal buffering, the SN74ABT8543DL from Texas Instruments is an excellent choice. Its robust design, combined with the quality and support from a leading semiconductor manufacturer, makes it a versatile component for any high-speed digital system.
