DESCRIPTION
The DS1020 Programmable 8-Bit Silicon Delay Line consists of an 8-bit, user-programmable CMOS
silicon integrated circuit. Delay values, programmed using either the 3-wire serial port or the 8-bit
parallel port, can be varied over 256 equal steps. The fastest model (-15) offers a maximum delay of
48.25 ns with an incremental delay of 0.15 ns, while the slowest model (-200) has a maximum delay of
520 ns with an incremental delay of 2 ns. All models have an inherent (step-zero) delay of 10 ns. After
the user-determined delay, the input logic state is reproduced at the output without inversion. The
DS1020 is TTL- and CMOS-compatible, capable of driving 10 74LS-type loads, and features both rising
and falling edge accuracy.
The all-CMOS DS1020 integrated circuit has been designed as a reliable, economic alternative to hybrid
programmable delay lines. It is offered in a standard 16-pin auto-insertable DIP and a space-saving
surface mount 16-pin SOIC.
