ON Semiconductor 74VCX162373MTD Low Voltage 16-Bit Transparent Latch

The 74VCX162373MTD from ON Semiconductor is a high-performance, low-voltage 16-bit transparent latch with 5V tolerant inputs and outputs. Designed for use in systems that require low power consumption and high data throughput, this device is suitable for a wide range of applications including telecommunications, computing, and industrial equipment.

This latch operates from a 1.65V to 3.6V VCC supply, making it ideal for interfacing with 3.3V systems while also being tolerant to 5V signals, allowing for a smooth integration with legacy systems. The 74VCX162373MTD is part of the VCX family, which is known for its low noise, high-speed operation, and low power dissipation.

Featuring a bus-hold circuitry that eliminates the need for external pull-up or pull-down resistors, this device simplifies board design and reduces board space requirements. The latch is organized as two 8-bit latches with separate output-enable (OE) inputs for each section. This allows for greater flexibility in controlling the flow of data.

The product comes in a 48-pin TSSOP (Thin Shrink Small Outline Package) that is designed for space-saving on PCBs and ensures a reliable connection in a small footprint. The 74VCX162373MTD supports the industrial temperature range of -40°C to +85°C, ensuring stable operation under varying environmental conditions.

Key features of the 74VCX162373MTD include:

• Low voltage operation: 1.65V to 3.6V
• High-speed operation: tPD 3.8ns (max) at 3.3V
• Power-down high impedance inputs and outputs
• 5V tolerant inputs and outputs
• Supports live insertion and withdrawal (partial-power-down mode)
• Static Drive (IOH/IOL): ±24 mA at 3.0V
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 300 mA
• ESD performance: Human-body model > 2000V, Machine model > 200V
• Package: 48-pin TSSOP

The 74VCX162373MTD is a robust and versatile component that ensures high-speed data storage and retrieval, making it an excellent choice for designers looking to optimize their digital systems for speed and power efficiency.
