| Description | The HC690/691/692/693 are high speed CMOS COUNTER/REGISTER fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption... |
| Features |
l circuit is composed of 3 stages including buffer output, which offers high noise immunity and stable output. These devices incorporate a synchronous counter, four-bit D-type register, and quadruple two-line to one-line multiplexers with three-state outputs in a single 20-pin package. The counter can be programmed from the data inputs and have enable P and enable T inputs and a ripplecarry output for easy expansion. The register/counter select input, R/C, selects the counter when low or the register when high for the threestate outputs, QA, QB, QC, and QD. If the LOAD input (LOAD) is held ”L”... |
