Logic-Latches play a vital role in many complex digital systems. One such latches is the 74FCT163373APAG, which is a 16-bit static CMOS latch featuring an innovative input design for power efficient operation. It includes a dual-bit latch for each positive and negative logic, an input that inhibits the corresponding output, and a wide power supply range from 3.3 to 5.5V. The 74FCT163373APAG latch offers high performance with low power consumption, making it ideal for a variety of applications.

The primary application field and working principle of the 74FCT163373APAG latch is in the context of memory storage. It is designed to complement the 74FCT163674APAG family of fast static RAM memory products. This latch is designed to operate as an address latch, data in/out register, datapath register, address register, data register, port latch, and multiplexer enablement. The latch is constructed with a differential address bus setup and a built-in synchronous latch to ensure that each stage of data is reliably latched without delay. The latch maintains stable data when the power is off, which allows for the consistent operation of RAM and other memory ICs even when power is removed.

The 74FCT163373APAG latch works using a pair of CMOS inverters, which act as a single latch with differential input and output. In operation, one of the CMOS inverters pulls the input signal to the "on" state and the other inverter pulls the output signal to the opposite "off or low" state. The latch output is a full-symmetrical two-level signal in which both logic levels are stable and neither has priority over the other. The individual elements of the differential latch are designed to be compatible with a wide range of inputs. For example, the latch is compatible with non-inverting, neutralizing and non-glitch inputs. This allows the latch to be used to reliably store data in TTL, CMOS and other logic standards.

The 74FCT163373APAG latch also features input enablement and a wide power supply range. The enablement feature allows the latch to maintain stable data without requiring the address and data bus changes to activate it. The input enablement also has an inhibit input that can be used to force the output low (disable the latch) when addresses or data changes are not required. This feature can also be used to completely isolate the device from the data bus. The wide power supply range from 3.3V to 5.5V minimizes the power consumption and allows the device to be used in a wide range of applications. In addition, this device features a high-speed turn-off precharge for faster access to the output. The latch is also fabricated with reliable CMOS technology for improved power efficiency and noise immunity.

In conclusion, the 74FCT163373APAG latch is an excellent choice for memory storage applications. It is designed with a differential address bus setup, a built-in synchronous latch, and wide power supply range to ensure reliable operation. The device also features input enablement, an inhibit pin and a high-speed turn-off precharge for faster access to the output. By combining high performance and low power consumption, the 74FCT163373APAG latch is suitable for a variety of applications.
