The CD4508BNSR is a dual 4-input NOR-gate latch with bipolar Schottky DTL stages. It is classified as a part of the Logic-Latches family due to its ability to store digital data. The purpose of this article is to discuss the application fields and working principle of the CD4508BNSR.

The CD4508BNSR is used in applications such as automated switching and robotic control. It is capable of controlling motor position, limit switches, and solenoids. It can also be used in communication systems such as memory address decoding, data path delay and clock synchronization.

The CD4508BNSR has two NOR gates, one set-reset latch, and one output buffer. The NOR gates are the core of the chip and are responsible for storing digital logic levels. The inputs of the gates are labeled A, B, C and D which are used to control the gates. The output of the gate is labeled Q. The gates are configured such that when the inputs A and B are equal to logical true, the gate will be set (Q = 1). If the inputs C and D are equal to logical true, the gate will be reset (Q = 0).

The NOR gates are connected to a latch which is designed to store digital data. When A and B are equal to logical true, the latch is set. This means that the output of the latch will remain at logical true until A and B are equal to logical false. Similarly, if C and D are equal to logical true the latch will be reset, meaning the output of the latch will remain at logical false until C and D are equal to logical false.

The output buffer is responsible for driving a load, this is essential in applications that require a high current. The output buffer increases the current handling capacity of the chip while ensuring low power consumption.

In summary, the CD4508BNSR is a dual 4-input NOR-gate latch with bipolar Schottky DTL stages which is mainly used in automated switching and robotic control applications. The CD4508BNSR has two NOR gates and one set-reset latch which are responsible for storing digital information. The output buffer is used to drive a load which is useful in applications that require a high current.
