Logic - Counters, Dividers
The SN74ALS163BDR is a low-cost, high-performance asynchronous presettable up/down counter containing four either 4-bit or 5-bit counters with modulo up to 26. The SN74ALS163BDR is designed to implement various standard synchronous counter functions including programmable division and maximum count. It is a fully synchronous, presettable up and down counter where the count is controlled by a single mode bit and an up/down line. The counters can be used as dividers or frequency dividers as well as for frequency division, as long as the clock is fast enough for it to handle the data. In addition, the counters can also be used as modulo or divide-by-N counters.
The SN74ALS163BDR can be operated from either a single-phase or a five-phase clock. It features a unique master-slave design for up/down counting, allowing for different frequency sources to be connected to the master and the slave counters. The device also offers a low power mode in which the slave counters are turned off when not needed, reducing the power used. The SN74ALS163BDR also offers a simple programmable logic interface that can be used to control how and when the counters will reset. This interface is designed to provide a user-friendly way to connect to and control a wide range of devices like registers, multiplexers, dividers, buffers, and other digital signal processing devices.
The SN74ALS163BDR contains four separate counters, each featuring 4-bit or 5-bit width, depending on the type of counter chosen. Each counter also includes a/an asynchronous/synchronous preset as well as a cascade port that allows the counters to be connected in series. The data inputs for each counter can be programmed to change from TTL logic levels to CMOS logic levels. This allows the counters to be used with a wide range of logic family devices. Additionally, each counter can be configured in various clocking modes, such as rising-edge triggered, falling-edge triggered, and synchronous-mode clocking.
The SN74ALS163BDR can also be used in application where multiple counting steps are required. Each counter can be programmed to count up to the desired number (4 or 5 bit) in its internal register. It then passes the count data to the next counter, which uses the data to count up or down from the previous one. This is especially useful for frequency or pulse division as well as for programs or routines that require multiple counting steps to compare numbers or perform operations.
The SN74ALS163BDR is manufactured in a variety of package sizes and with a flexible lead layout for effortless integration into existing or custom circuits. The device is designed with the intention of interfacing with other SN74ALS163BDRs on the same board. It also has built-in self-test capability, which ensures correct connection between the various counters and related logic. Furthermore, the device can be directly connected to interrupt pins, reducing the need to use additional logic-level elements to do so.
The SN74ALS163BDR is an excellent choice for a wide range of applications, and is designed to meet a variety of needs. Its wide range of features, such as its low-power capability, wide input and output options, and programmable logic interface, make it a superior option for any synchronous counter design.
