General Description

IN P0-P7 GND OUT VCC S E C Q D - Delay Input - Parallel Program Pins - Ground - Delay Output - +5 Volts - Mode Select - Enable - Serial Port Clock - Serial Data Output - Serial Data Input DESCRIPTION The DS1021 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 faster model (-25) offers a maximum delay of 73.75 ns with an incremental delay of 0.25 ns, while the slower model (-50) has a maximum delay of 137.5 ns with an incremental delay of 0.5 ns.

Key Features

All-silicon time delay Models with 0.25 ns and 0.5 ns steps Programmable using 3-wire serial port or 8bit parallel port Leading and trailing edge accuracy Economical Auto-insertable, low profile, 16-pin SOIC package Low-power CMOS TTL/CMOS-compatible Vapor phase, IR and wave solderable PIN.
