The SN74ALVCH162260 from Texas Instruments is a high-performance, 12-bit to 24-bit multiplexed D-type latch designed for use in systems that demand low-voltage and high-speed data storage and multiplexing. This integrated circuit (IC) is part of the Advanced Low-Voltage CMOS (ALVC) family and is optimized for 2.5V to 3.3V VCC operation while maintaining compatibility with 5V I/O logic levels.

With its dual functionality, the SN74ALVCH162260 can be used either as two 12-bit latches or one 24-bit latch. This feature provides flexibility in system design and helps in saving board space by reducing the number of components required. The device is equipped with two sets of address inputs (1A to 12A and 1B to 12B), two sets of data inputs (1D to 12D and 1E to 12E), and two sets of output enables (1OE and 2OE) for independent control of each section.

Featuring 3-state outputs, the SN74ALVCH162260 allows for connection to a bus-oriented system without the need for external pull-up resistors. When the output-enable (OE) input is high, the outputs are in the high-impedance state, which is essential for multiplexing and bus-driving applications.

The latch also supports edge-triggered data storage: data on the D or E inputs can be stored in the latch either on the rising or falling edge of the clock input, depending on the latch mode selected. This versatility makes the SN74ALVCH162260 suitable for a variety of applications, including data storage, address latching, and bus interfacing in computer and telecommunications systems.

Key features of the SN74ALVCH162260 include:

• Operates from 2.5 V to 3.3 V
• High-speed data storage and multiplexing
• Supports mixed-mode signal operation (5V input and output voltages with 3.3V VCC)
• Low power consumption
• ±24-mA output drive at 3.3 V
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 250 mA per JESD 17
• ESD protection exceeds JESD 22

Whether you're designing high-speed data paths, complex telecommunications infrastructure, or advanced computing systems, the SN74ALVCH162260 offers the performance and reliability expected from a leader in semiconductor solutions like Texas Instruments.
