The 74HC5555N,112 is a programmable timer/oscillator from Texas Instruments, that is often used in clock/timing applications. It is a high, medium-speed bipolar Schottky device and is suitable for applications such as motor drive clocks, pulse generation and general timing. The device is divided between a single-chip oscillator, which comprises the timing and an analog function, and a programmable, non-volatile memory, which comprises the timer data.

The core of the 74HC5555N,112 is a simple CMOS/AKAI/Schottky design, which allows the device to operate as an oscillator and as a programmable timer. The device is able to generate a wide range of frequencies, ranging from 0.1Hz to 5MHz. This is achieved thanks to its two-section timing circuitry, which consists of a timing capacitor and a programmable resistive element. The resistor has resistances ranging from 1Ω to 10MΩ, and the capacitor, depending on the version, can range from a few picofarads to tens of nanofarads.

The 74HC5555N,112 also features a two-way programmable logic feature. This allows the user to choose from a variety of logic functions to operate the timer, such as a low level logic, a high level logic or a Schmitt trigger. This feature reduces the component count and thus simplifies the PCB design. Additionally, the device has a power-down mode in which the timer can be stopped and the current consumption can be reduced to less than 1µA.

In general, the 74HC5555N,112 is a highly reliable, low cost and versatile timer/oscillator. It is ideal for clock/timing applications where flexibility and precise timing requirements are desired. The device is also capable of being programmed to suit the user’s specific needs, allowing for further cost savings and design flexibility. Furthermore, the device can be interfaced and controlled remotely, eliminating the need for human intervention and supplying increased reliability.
