HA19216/MP
6-Bit Flash Type Analog-to Digital Converter
Description
The HA19216/MP bipolar LSI performs high speed 6-bit A/D conversion. Digital data output and clock input terminals are compatible with TTL and CMOS. The HA19216/MP are designed for video signal processing application.
Features
* 6-bit resolution (including overflow) * 6-bit latched three-state outputs * Maximum conversion Rate: 20 Msps (Min) * Single Power Supply: +5 V * Digital data output, high impedance state control and clock input terminals compatible with TTL and CMOS * Needs no sample and hold circuit * 18-pin DIP package and 28-pin surface mount package. * Output current: IOL = 1.4 mA (guaranteed) IOH = -5 mA (guaranteed)
Application
* Pattern recognition using a computer * High-speed measuring instruments
