CD74HC190E Description

Short technical summary and product information.

The CD74HC190E from Texas Instruments is a presettable synchronous BCD decade up/down counter. This integrated circuit operates with a voltage range of 2V to 6V and features a maximum count rate of 35 MHz.

 

Designed for flexibility, the CD74HC190E supports both up and down counting modes, controlled by the D/U input. Asynchronous preset capabilities allow the counter to be loaded with a specific number via the preset data inputs (A-D) when the LOAD input is low. The synchronous counting operation occurs on the low-to-high transition of the clock signal when LOAD is high and count enable (CTEN) is low.

 

This counter is available in a 16-PDIP package suitable for through-hole mounting. It operates across a wide temperature range of -55°C to 125°C, making it suitable for various environmental conditions. The device offers balanced outputs and high-speed performance with a typical propagation delay between 10-50ns.

 

Key features include standard CMOS input types and push-pull output types. The CD74HC190E is designed for applications requiring precise counting and control, offering significant power reduction compared to LS-TTL logic.
