ON Semiconductor MC74LCX16373G Low Voltage 16-Bit Transparent Latch

The MC74LCX16373G is a high-performance, 16-bit transparent latch designed and manufactured by ON Semiconductor. This integrated circuit is part of the LCX family, which is renowned for its low voltage operation and compatibility with 5V I/O systems. The device is optimized for use in systems that require high-speed data storage and transfer, while maintaining low power consumption and a small form factor.

Constructed with an advanced CMOS technology, the MC74LCX16373G operates at a voltage range of 2.3V to 3.6V, making it ideal for battery-operated and portable applications where power efficiency is crucial. Its low voltage operation does not compromise performance, as the device is capable of functioning at speeds comparable to 5V systems, ensuring quick data access and processing.

The latch features 16 D-type flip-flops with a common Latch Enable (LE) and Output Enable (OE) control, which allows for flexible control of data flow. When the LE input is high, the D-inputs are transparent to the outputs, and when LE is low, the data that meets the setup time is latched. The OE control enables the user to place the eight outputs in either a normal logic state or a high-impedance state, which is useful for interfacing with bus-oriented systems.

Besides its functional capabilities, the MC74LCX16373G boasts an impressive feature set that includes 5V tolerant inputs, which allow interface with 5V systems without the need for additional level shifting. The device also supports live insertion and withdrawal, minimizing system downtime during maintenance and upgrades. Furthermore, its I_OFF circuitry disables the outputs, preventing damaging current backflow when the device is powered down.

ON Semiconductor has housed the MC74LCX16373G in a 48-pin TSSOP package, ensuring a compact footprint suitable for space-constrained applications. The package is also lead-free and fully RoHS compliant, reflecting ON Semiconductor's commitment to environmental sustainability.

In summary, the MC74LCX16373G from ON Semiconductor is a versatile, low-voltage 16-bit transparent latch that offers high-speed operation, 5V tolerant inputs, and power-saving features, making it a strong choice for designers looking to optimize their digital systems for performance and efficiency.
