SN74LVTH16373DLG4

The SN74LVTH16373DLG4, introduced by Texas Instruments, is a high-performance logic latch device that is an integral part of a range of logic family products, including registers, counters, buffers and logic gates. This latch is targeted at portable and consumer applications, with moderate power and speed requirements.

The SN74LVTH16373DLG4 component is part of the LVT TTL (Low-Voltage Transistor-Transistor Logic) family of parts. TTL logic is incredibly popular and versatile, used for many decades for low-to-moderate speed applications. TTL has built-in logic hysteresis and protection logic components, which make the logic signals more immune to noise and transient signals from the environment and the power supply.

The SN74LVTH16373DLG4 is clocked and edge-triggered latch, meaning that the output state is conditioned only by the state of the inputs at the time of a rising or falling pulse (clock signal). This component contains 16 latches. It accepts data inputs on both positive and negative logic, meaning the logic states of the data inputs can be specified as either 0/1 or 1/0. The SN74LVTH16373DLG4 has a data valid time of 7 ns and a propagation delay of 4.5 ns.

The SN74LVTH16373DLG4 as a latch is ideal for applications where synchronization or temporary data storage required. This particular component can be used to store information from an input source, or provide memory of the data stream. The data are clocked into the latch, and the register can then hold the data until it is released or the output is reset. The SN74LVTH16373DLG4 can help to create logic functions such as toggle, half-and-half, or full adders.

The SN74LVTH16373DLG4 is primarily used in portable, consumer applications such as digital watches, pagers, cell phones, remote controls, and digital signal processing. As mentioned previously, the SN74LVTH16373DLG4’s logic hysteresis makes it ideal for these applications, as they are susceptible to electrical noise and transient signals.

The SN74LVTH16373DLG4 is a fixed supply voltage component; input high level must be greater than VCC and input low level must be lower than 0.8VCC. In addition, the component utilizes a component pin that serves as a power-on reset (POR). The POR pin is used to ensure that all of the component’s registers are set to the reset state upon power-up.

The SN74LVTH16373DLG4 component is manufactured using a small-outline package (SOP) and is offered in two versions: high speed, for increased performance, and low-power, for applications with power / energy constraints. The SOP package and various versions of the component make it a popular concept for designers wanting to deploy simple, yet powerful and efficient logic solutions.

In summary, the SN74LVTH16373DLG4 is a feature-rich logic latch component intended for use in consumer applications. It consists of 16 latches and is driven by either positive or negative logic. It has a propagation delay of 4.5 ns and also includes an power-on reset (POR) pin. The component is offered in two versions for increased performance or low power, and is manufactured in a small-outline package (SOP).
