M74HC153B1R is a quadruple 2-input multiplexer that can be used for a variety of applications such as signal switching, multiplexers, decoders, and address selection. It consists of four independent 2-input multiplexers with common select (S) inputs and individual enable (E) inputs. The four independent 2-input multiplexers make it possible to select one of four data inputs (D0-D3) to be routed to the output (Y). The device is a highly integrated multiplexer/switch device capable of performing the analog multiplexing function of selecting and routing logic signals with very high speed and low power consumption.

M74HC153B1R is a member of the Toshiba HC family, which has been long recognized as one of the most important types of circuit devices used in digital and analog designs. The M74HC153B1R operates using a two-level logic system. The logic inputs areA and B, supplying actual logic high and low levels from an external TTL/CMOS gate. The enable (E) inputs are also active low and must be driven high in order for the device to perform its multiplexing function. The device is designed with Schmitt trigger inputs on the A and B inputs, making it suitable for noisy environments and when used with very slow transition times.

The S input determines which of the four data inputs (D0-D3) will be connected to the output (Y). When the S input is logic high, the D0 input is connected to the output (Y). When the S input is logic low, the D1 input is connected to the output. The enable (E) input on each 2-input multiplexer must be driven high to allow the multiplexer to perform its operation. If the enable (E) input is driven low, the device will be in disable mode and the output will remain logic low regardless of the inputs.

M74HC153B1R can also be used for address selection when used with a counter. The counter provides the selection (S) input to the multiplexer, and the address lines of the memory provide the data input. By using the counter, the address of the memory can be changed in a systematic manner. The multiplexer can also be used as a data selector when connected to a data bus. In this case, the selection (S) inputs are connected to the data bus while the outputs of the multiplexer are connected to the required peripherals.

The fast operating speed and wide power supply range makes the M74HC153B1R suitable for a wide range of applications. It is capable of operating at a high speed of up to 25MHz, allowing for a fast data switching. Additionally, the power supply range of 2.7V to 5.5V makes it suitable for operation in both low power and high power applications. The M74HC153B1R also provides protection against electrical noise and fast switching for maximum protection against ESD/RE events.

Overall, M74HC153B1R is a very versatile device that can be used in many different types of applications due to its performance, low power consumption and reliability. It is an ideal choice for applications such as signal switching, multiplexers, decoders, address selection and data selection. Its fast operation and wide power supply range make it ideal for both high power and low power applications, making it a very versatile and reliable device.
