74HC90 (Decade, Divided by twelve AND binary counter- 4-BIT Binary Counter) 35C Tap/Double Tap Detection

Tap/Double Tap Detection

The 74HC174  are hex positive edge -triggered D-type flip-flops with individual data inputs (Dn) and outputs (Qn)

The multiple enable lines allow for the parallel expansion of decoders to create 4-to-16 line versions with no additional parts and 5-to-32 versions with the addition of a single inverter

Kit includes (As shown in Figure Below)

Micro-stepping capability (1/1

74HC90 (Decade, Divided by twelve AND binary counter- 4-BIT Binary Counter) 35C Tap/Double Tap Detectionhigh speed 4 bit ripple type counters partitioned into two sections. Each counter has a divide by two section and either a divide by five section which are triggered by a HIGH to LOW transition on the clock inputs. Each section can be used separately or tied together (Q to CP) to form BCD, bi quinary, modulo 12, or modulo 16 counters. All of the counters have a 2 input gated Master Reset (Clear), and the LS90 also has a 2 input gated Master Set
