HI3086
6-Bit, 140 MSPS, Flash A/D Converter
August 1997
Features
Description
The HI3086 is a 6-bit, high-speed, flash analog-to-digital con-
verter optimized for high speed, low power, and ease of use.
With a 140 MSPS encode rate capability and full-power analog
bandwidth of 200MHz, this component is ideal for applications
requiring the highest possible dynamic performance.

• CLK/2 Clock Output Pin
To minimize system cost and power dissipation, only a +5V
power supply is required. The HI3086’s clock input interfaces
directly to TTL, ECL, or PECL logic and will operate with single-
ended inputs. The user may select 16-bit demultiplexed output
or 8-bit single-channel digital outputs. The demultiplexed mode

rate. Operation in demultiplexed mode reduces the speed and
cost of external digital interfaces, while allowing the A/D
converter to be clocked to the full 140 MSPS conversion rate.

(With Reset Function)
Fabricated with an advanced bipolar process, the HI3086 is
provided in a space-saving 48-lead MQFP surface mount
plastic package and is specified over the -20 C to 75 C
temperature range.
• Compatible with ECL, PECL and TTL Digital Input Levels
• Direct Replacement for Sony CXA3086
