The IC component SN74HC193QPWRQ1 is a high-speed synchronous up/down counter designed for automotive applications. It comes in a small, space-saving TSSOP-16 package and operates over a wide voltage range of 2V to 6V. This IC is from the 74HC family of components, which are CMOS-based integrated circuits known for their high-speed operation and low power consumption.
The SN74HC193QPWRQ1 offers several key features that make it suitable for automotive applications:
1. Synchronous Operation: This IC makes use of synchronous clock inputs to ensure accurate and reliable counting. The counter's outputs change simultaneously with the clock input transitions, maintaining synchronization.
2. Up/Down Counting Modes: The SN74HC193QPWRQ1 can be configured to count up or down based on the input control signals. By toggling the up/down control pin, the counter can switch between incrementing or decrementing the count value.
3. Asynchronous Load/Ripple Carry Input: This IC features an asynchronous load input, allowing users to preset the count value by activating this input using a parallel data input. It also includes a ripple carry output, which can be connected to the carry input of other counters for cascading multiple counters together.
4. Schmitt-Trigger Inputs: The inputs of the SN74HC193QPWRQ1 have Schmitt-trigger characteristics, which enable them to have hysteresis and provide noise immunity
