SN74S112ANSRE4

SN74S112ANSRE4 is a flip-flop logic device which belongs to the family of logic - flip flops. It is a versatile logic element which can be used for various applications.

Overview

The SN74S112ANSRE4 is an asynchronous flip-flop circuit with two active-low outputs, D and DnQ. The device features an asynchronous reset (RESET) and complementary outputs (D and DnQ) that allow for source-coupled logic applications. The RESET has active-low input. The device also has a positive-true clock (CLK) input and an active-low enable (EN) input. The device can operate at a voltage range of 2.3V to 5.5V, and operates with a maximum clock frequency of 25 MHz.

Applications

The SN74S112ANSRE4 is a versatile logic device which can be used in many different applications. It can be used as a latch to store data, as a memory circuit, as a counter and a register, as the basis for data communications, as the basis for address bus decoding, as the basis for data bus multiplexing and for other logic applications. The SN74S112ANSRE4 is especially useful in applications which require high-speed performance and low power consumption. The device can be used as a latch in high-speed applications, as a memory circuit in low-power applications, and as a counter in applications where high reliability is required.

Working Principle

The SN74S112ANSRE4 is an asynchronous flip-flop circuit which consists of two flip-flop circuits, the D and DnQ flip-flops. The device is triggered by the clock (CLK) input. When the CLK is at logic low, the device holds its current state on both the D and DnQ outputs. When the CLK is at logic high, the device updates its state on the next rising edge. The device also has an active-low enable (EN) input which allows the device to be enabled or disabled depending on the logic state of the EN pin. When the EN input is low, the device is enabled and the clock will affect the state of the outputs, otherwise the device is disabled and the output will maintain its previous state. The device also has an asynchronous reset (RESET) which allows the device to be reset to a known state (low) quickly regardless of the current state of the D and DnQ outputs. The RESET signal is an active-low input, meaning that a logic low signal will reset the device to the logic low state.

Conclusion

The SN74S112ANSRE4 is a versatile flip-flop logic device which can be used for various applications. It has an asynchronous reset (RESET) and complementary outputs (D and DnQ) which allow for source-coupled logic applications. The device can operate at a voltage range of 2.3V to 5.5V and has a maximum clock frequency of 25 MHz. The device is especially useful in applications which require high-speed performance and low power consumption.
