STMicroelectronics 74LVX373MTR Octal Transparent Latch

The 74LVX373MTR by STMicroelectronics is a high-speed, low-voltage octal transparent latch with 3-state outputs, belonging to the LVX family which is fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. This integrated circuit is designed to be used in applications that require the capture and retention of data during transient conditions. With its 20-lead Micro Package (TSSOP), the 74LVX373MTR is optimized for enhanced system integration and minimal space usage.

This device is characterized for operation from -40°C to 85°C, making it suitable for industrial temperature ranges. It features a 5V tolerant input/output for interfacing with 5V logic levels, which is crucial for mixed-voltage applications. The latch is transparent with the latch enable (LE) input high, allowing data at the inputs to pass through to the outputs. When LE is low, the data that meets the setup time is latched at the outputs and held stable, enabling the device to be used in bus-oriented systems.

The 74LVX373MTR is equipped with eight latches with three-state standard outputs. When the output enable (OE) input is high, the outputs are in a high impedance state, which is essential for bus-oriented applications. The low quiescent current and low operational current of this device make it ideal for low-power applications. The fast propagation delay ensures quick data transfer, enhancing the performance of the system it is integrated into.

Key features of the 74LVX373MTR include:

• High-speed: typical t<sub>PD of 5.2ns at V<sub>CC = 3.3V
• 5V tolerant inputs and outputs for interfacing with 5V logic
• Power-down protection on inputs and outputs
• Supports live insertion and withdrawal (partial power-down mode)
• Low power consumption: I<sub>CC = 4µA maximum at T<sub>A = 25°C
• ESD performance: HBM > 2000V; MM > 200V

The 74LVX373MTR is ideal for a wide range of applications including memory address latching, data multiplexing, and as a buffer for interfacing to bus lines. Its robust design and advanced technology make it a reliable choice for designers looking for a high-performance latch solution.
