HI5714/4CBS2503

Encoders, Decoders, Converters Overview

The HI5714 is a high-speed, monolithic 8-bit analog-to-digital converter manufactured by Harris Corporation. It utilizes a charge redistribution architecture to achieve rapid conversion times. The device operates with a single +5V power supply and features a TTL-compatible input for the clock signal. Key electrical parameters include an 8-bit resolution, a maximum sampling rate of 250 MSPS, and a typical conversion time of 3.6 ns. The input voltage range is specified from 0V to Vref, where Vref can be set externally. The component is housed in a 20-pin ceramic flatpack package (CQCC) or plastic DIP, designed for demanding applications requiring fast data acquisition.

Encoders, Decoders, Converters Procurement Notes

Verify manufacturer authenticity carefully due to the age of this component. Check for original Harris markings versus later rebrands. Confirm package integrity and pin condition. Request detailed test reports if available. Ensure compliance with current environmental regulations regarding lead content in legacy components.

Encoders, Decoders, Converters Selection Notes

Consider the HI5714 when 8-bit resolution at 250 MSPS is required. Evaluate thermal management needs for high-frequency operation. Compare against newer CMOS alternatives for power efficiency. Verify reference voltage stability requirements. Assess board space constraints for the specific package type selected.

Encoders, Decoders, Converters Part Context

Harris Semiconductor was a prominent manufacturer of linear and mixed-signal ICs before being acquired by Intersil, which later merged with Renesas Electronics. The HI5714 belongs to a family of high-speed ADCs produced during the era when Harris dominated the analog semiconductor market. This part represents legacy technology still used in maintenance and specialized high-speed applications.

Encoders, Decoders, Converters Replacement Considerations

Direct pin-for-pin replacements may be limited. Consider the AD9200 or similar modern successors for improved performance. Verify compatibility with existing clock drivers and reference circuits. Check for updated packaging options and availability through authorized distributors.
