说明

The DS1021 is an 8-bit programmable delay line that reproduces an input logic state at the output after a user-programmed delay. It is similar to the DS1020 but with the economy of reduced specifications. Available in two versions, total delays are varied over 256 steps and range from an inherent 10ns minimum delay in both versions to a maximum delay of 137.5ns. The DS1021 can be programmed over the 3-wire serial port or the 8-pin parallel port. The DS1021 is TTL- and CMOS-compatible and capable of driving up to ten 74LS-type loads. Both leading- and trailing-edge accuracy are specified.

The DS1021 is an effective, economical solution to the designer working with the complex timing requirements of mismatched ASICs or other components, or with the strict timing tolerances of increasing system clock rates. With the DS1021's programmable outputs, the user can precisely adjust timing to application needs and improve system performance. Innovative circuit designs and factory laser or EPROM trimming enhance accuracy without the need for external components, saving cost and space.
