ON Semiconductor MC74LCX16373DTR Low Voltage 16-Bit Transparent Latch

The MC74LCX16373DTR from ON Semiconductor is a high-performance, 16-bit transparent latch designed for use in 3.3 V LVTTL/LVCMOS systems. This integrated circuit is part of ON Semiconductor's LCX portfolio, which is renowned for its low-voltage operation and high-speed interface technology. The device is optimized for low noise and reduced power consumption, making it suitable for a wide range of applications including telecommunications, computing, and industrial controls.

The device is characterized by its 16 transparent D-type latches with 3-state outputs. Each latch is D-type, meaning it captures the state of the data inputs whenever the latch-enable (LE) input is high. The data is held stable on the output when LE is low, providing a transparent latch operation. The 3-state outputs allow for direct connection to a bus or data lines, as they can be placed in a high-impedance state, effectively disconnecting the latch output from the bus.

One of the key features of the MC74LCX16373DTR is its 5V tolerant inputs, which enable the device to be used in mixed-voltage environments without the need for additional level shifting. This is particularly advantageous in systems where 5V and 3.3V logic need to interface seamlessly. The device also offers support for live insertion and withdrawal, meaning it can be added or removed from a system without the need to power down the entire system.

Designed with an operating voltage range of 2.3V to 3.6V, the MC74LCX16373DTR provides a flexible solution for power-sensitive designs. The device's performance is guaranteed over the full voltage range, with typical data propagation delays as low as 5.5ns and a maximum clock frequency of 150MHz, ensuring swift and reliable data handling in high-speed applications.

ON Semiconductor has packaged the MC74LCX16373DTR in a TSSOP-48 (Thin Shrink Small Outline Package), offering a space-saving footprint for PCB layouts. The package is also RoHS compliant, adhering to environmental standards and regulations.

Overall, the MC74LCX16373DTR is an excellent choice for designers looking for a high-speed, low-voltage transparent latch with the robustness and reliability that ON Semiconductor products are known for.
