Hot-selling and scarce Z8430PS Counter Timer Circuit DIP28 spot stock

Product Descriptions

The Z80 CTC, hereinafter referred to as Z80 CTC or CTC,four-channel counter/timer can be programmed by system software for a broad range of counting and timing applica-tions. The four independently programmable channels ofthe Z80 CTC satisfy common microcomputer system re-quirements for event counting, interrupt and interval timing,and general clock rate generation.

​

System design is simplified because the CTC connects directly to both the Z80 CPU and the Z80 SIO with no additional logic. In larger systems, address decoders and buffers may be required.

Product Features

Fourindependentlyprogrammable counter/timerchannels, each with a readable downcounter and aselectable 16 or 256 prescaler. Downcounters arereloaded automatically at zero count.

Selectable positive or negative trigger initiates timer operation.

Three channels have Zero Count/Timeout outputscapable of driving Darlington transistors. (1.5 mV @ 1.5V)

NMOS version for cost sensitiveperformance solutions.

CMOS version for the designs requiring low power consumption
