The 74LCX373TTR is a high-performance, low-voltage octal transparent latch designed by STMicroelectronics. This advanced CMOS device is tailored for optimal performance in 3.3V systems, but it is also 5V tolerant, ensuring compatibility with older voltage levels. The 74LCX373TTR is part of STMicroelectronics' LCX family, known for its low power consumption and high noise immunity.

Key Features

• Low Voltage Operation: The 74LCX373TTR operates at a nominal voltage of 3.3V, making it suitable for modern, low-power applications.
• 5V Tolerant Inputs: Inputs can tolerate 5V, ensuring the device can interface with both 3.3V and 5V systems without the need for additional level shifting.
• High-Speed Performance: This device boasts a high-speed performance, which is essential for systems that require fast data throughput.
• Power-Down High-Impedance Inputs and Outputs: It features a power-down high-impedance state that minimizes power consumption when not in active use.
• Support for Live Insertion: The 74LCX373TTR is designed to support live insertion and withdrawal without glitching, allowing for maintenance and upgrades without system downtime.
• Transparent Latches: Data inputs appear at the outputs when the latch-enable (LE) input is HIGH, and the data is latched when LE is taken LOW.
• Bus-Hold Data Inputs: The device includes bus-hold circuitry, eliminating the need for external pull-up resistors.

Applications

The versatility of the 74LCX373TTR makes it ideal for a wide range of applications, including:
