Overview
The 74HC393DB,112 is a dual 4-bit binary ripple counter integrated circuit produced by NXP USA Inc. This component is part of the 74HC series and is designed for use in a variety of digital counting applications. It features two independent 4-bit counters, each with a clock input, an overriding asynchronous master reset input, and four buffered parallel outputs. The counters advance on the HIGH-to-LOW transition of the clock input and can be reset asynchronously by a HIGH on the master reset input.

- What is the package type of the 74HC393DB,112?
The package type is 14-SSOP (0.209", 5.30mm Width).
- What is the operating temperature range of the component?
The operating temperature range is from -40°C to 125°C.
- How many bits per element does the counter have?
Each counter element has 4 bits.
- What is the maximum count rate of the counter?
The maximum count rate is 107 MHz).
- Is the 74HC393DB,112 RoHS compliant?
Yes, it is ROHS3 compliant).
- What is the moisture sensitivity level (MSL) of the component?
The MSL is 1 (Unlimited)).
- How does the asynchronous master reset input function?
A HIGH on the master reset input clears the counter stages and forces the outputs LOW, independent of the state of the clock input).
