SN74AHC573QPWRQ1 Octal Transparent D-Type Latches by Texas Instruments

The SN74AHC573QPWRQ1 is a high-performance, octal transparent D-type latch designed for automotive and industrial applications. Manufactured by Texas Instruments, this integrated circuit is part of their AHC (Advanced High-Speed CMOS) family, which is known for its robustness and reliability in demanding environments. The device is specifically created to meet the stringent requirements of the automotive industry, complying with the automotive electronics council's specifications for stress-resistant components.

This latch features eight D-type latches with 3-state outputs, allowing for the temporary storage of data and providing the option to isolate the bus lines during memory updating. Each latch is capable of directly driving 15 LSTTL loads, making it suitable for interfacing with a wide range of logic families. The high-current outputs of ±8-mA at 5 V significantly enhance the SN74AHC573QPWRQ1's drive capabilities.

The device operates over a broad voltage range of 2 V to 5.5 V, ensuring compatibility with various systems and enabling it to support both 3.3 V and 5 V logic levels. The low power consumption of the AHC series is particularly beneficial for battery-operated and power-sensitive applications, without compromising on speed or performance.

For ease of implementation, the SN74AHC573QPWRQ1 comes in a TSSOP (Thin Shrink Small Outline Package) form factor, designated by the PWR suffix in its part number. The package is designed to optimize board space without sacrificing thermal performance and is well-suited for surface-mount technology (SMT).
