The HI21421 is an 8-bit, 40MHz, high speed D/A converter.

The converter incorporates an 8-bit input data register with

blanking capability, and current outputs. The HI21421 fea-

tures low glitch outputs. The architecture is a current cell

arrangement to provide low linearity errors.

The HI21421 is available in an Industrial temperature range

and is offered in a 24 lead (200 mil) SOIC plastic package.
