Surface Mount Quadrature Decoder/Counter Interface ICs Technical Data HCTL-2016 #PLC HCTL-2020 #PLC Features • 20 Pin PLCC Surface Mount Package • All Features of the HCTL2016 and HCTL-2020 PDIP Description The HCTL-2016 #PLC and HCTL2020 #PLC are quadrature decoder/counter interface ICs in a 20 pin PLCC (plastic leaded chip carrier) surface mount package. These CMOS ICs interface incremental encoders to microprocessors by performing the quadrature decoder, counter, and bus transfer functions. The HCTL-2016 #PLC and HCTL2020 #PLC have all of the same features, functions, and operating characteristics as the HCTL-2016 and HCTL-2020 PDIP (plastic dual-in-line package). Applications For further information on the operation and function of the HCTL-2016 #PLC and 2020 #PLC, please refer to the HCTL2000/HCTL-2016/HCTL-2020 data sheet. Note: Agilent Technologies encoders are not recommended for use in safety critical applications. Eg. ABS braking systems, power steering, life support systems and critical care medical equipment. Please contact sales representative if more clarification is needed. Typical applications include interfacing incremental encoders to microprocessors and interfacing digital potentiometers to digital data input buses. 2 1 20 19 D1 V DD 3 CLK 20 19 D0 1 SEL V DD 2 D1 CLK 3 D0 SEL Pinouts OE 4 18 D2 OE 4 18 D NC 5 17 D3 U/D 5 17 D3 2 NC 6 16 NC NC 6 16 CNT DCDR RST 7 15 NC RST 7 15 CNT CAS CH B 8 14 D4 CH B 8 14 D4 HCTL-2016 #PLC D5 D6 7 D V SS 9 10 11 12 13 CH A D5 D6 D7 V SS CH A 9 10 11 12 13 HCTL-2020 #PLC ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC DISCHARGE.
