IW4042B QUAD CLOCKED «D» LATCH High-Voltage Silicon-Gate CMOS CD4042B types contain four latch circuits, each strobed by a common clock. Complementary buffered outputs are available from each circuit. The impedance of the n- and p-channel output devices is balanced and all outputs are electrically identical. Information present at the data input is transferred to outputs Q and Q during the CLOCK level which is programmed by the POLARITY input. For POLARITY = 0 the transfer occurs during the 0 CLOCK level and for POLARITY = 1 the transfer occurs during the 1 CLOCK level. The outputs follow the data input providing the CLOCK and POLARITY levels defined above are present. When a CLOCK transition occurs (positive for POLARITY = 0 and negative for POLARTY = 1) the information present at the input during the CLOCK transition is retained at ORDERING INFORMATION the outputs until an opposite CLOCK transition occurs.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 IW4042B DC ELECTRICAL CHARACTERISTICS(Voltages Referenced to GND) Guaranteed Limit VСС Symbol Parameter Test Conditions V ≥-55°C 25°C ≤125 °C VOUT=0.5 V or VCC - 0.5 V 3.5 3.5 3.5 VIH Minimum High5.0 VOUT=1.0 V or VCC - 1.0 V 7 7 7 Level Input 10 V =1.5 V or V 1.5 V OUT CC 11 11 11 Voltage 15 VOUT=0.5 V or VCC - 0.5 V 1.5 1.5 1.5 VIL Maximum Low 5.0 VOUT=1.0 V or VCC - 1.0 V 3 3 3 Level Input 10 VOUT=1.5 V or VCC - 1.5 V 4 4 4 Voltage 15 4.95 4.95 VIN=GND or VCC 4.95 VOH Minimum High5.0 9.95 9.95 9.95 Level Output 10 Voltage 15 14.95 14.95 14.9 5 0.05 0.05 VIN=GND or VCC 0.05 VOL Maximum Low5.0 0.05 0.05 0.05 Level Output 10 0.05 0.05 0.05 Voltage 15 IIN Maximum Input VIN= GND or VCC 18 ±0.1 ±0.1 ±1.0 Leakage Current 30 1 VIN= GND or VCC 1 IСС Maximum 5.0 60 2 2 Quiescent Supply 10 120 4 4 Current 15 600 20 20 (per Package) 20 VIN= GND or VCC IOL Minimum Output 0.51 0.36 0.64 Low (Sink) VOL=0.4 V 5.0 0.9 1.3 1.6 Current 10 VOL=0.5 V 2.4 3.4 4.2 15 VOL=1.5 V VIN= GND or VCC IOH Minimum Output -1.6 -1.15 -2.0 5.0 High (Source) VOH=2.5 V 5.0 -0.64 -0.51 -0.36 Current VOH=4.6 V -0.9 -1.3 -1.6 10 VOH=9.5 V -2.4 -3.4 -4.2 15 VOH=13.5 V 3 Unit V V V V µA µA mA mA IW4042B AC ELECTRICAL CHARACTERISTICS(CL=50pF, RL=200 kΩ, Input tr=tf=20 ns) Guaranteed Limit VCC Symbol Parameter V ≥-55 25°C ≤125 °C °C 900 450 450 tPLH, Maximum Propagation Delay, Clock to 5.0 400 200 200 tPHL Q (Figure 1) 10 320 160 160 15 1000 500 500 tPLH, Maximum Propagation Delay, Clock to 5.0 460 230 230 tPHL Q (Figure 1) 10 360 180 180 15 440 220 220 tPLH, Maximum Propagation Delay, Data to Q 5.0 220 110 110 tPHL (Figure 2) 10 160 80 80 15 600 300 300 tPLH, Maximum Propagation Delay, Data to Q 5.0 300 150 150 tPHL (Figure 2) 10 200 100 100 15 400 200 200 tTLH, tTHL Maximum Output Transition Time, Any 5.0 200 100 100 Output (Figure 1) 10 160 80 80 15 CIN Maximum Input Capacitance 7.5 TIMING REQUIREMENTS(CL=50pF, RL=200 kΩ, Input tr=tf=20 ns) Guaranteed Limit VCC Symbol Parameter V ≥25°C ≤125° C 55°C 400 200 200 tw Minimum Pulse Width, Clock (Figure 1) 5.0 200 100 100 10 120 60 60 15 100 50 50 tsu Minimum Setup Time, Data to Clock 5.0 60 30 30 (Figure 1) 10 50 25 25 15 240 120 120 th Minimum Hold Time, Clock to Data 5.0 120 60 60 (Figure 1) 10 100 50 50 15 Not rise or fall t r, tf Maximum Input Rise or Fall Time, 5.0 time sensitive Clock (Figure 1) 10 15 4 Unit ns ns ns ns ns pF Unit ns ns ns µs IW4042B Figure 1.
