DS1020集成電路（IC）的延遲線(xiàn)規(guī)格書(shū)PDF中文資料

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.
