1 / 7 page MOTOROLA CMOS LOGIC DATA MC14415 290 Quad Precision Timer/Driver MC14415 quad timer/driver is constructed with complementary MOS enhancement mode devices. The output pulse width of each digital timer is a function of the input clock frequency. Once the proper input sequence is detected the output buffer is set (turned on), and after 100 clock pulses are counted, the output buffer is reset (turned off). The MC14415 was designed specifically for application in high speed line printers to provide the critical timing of the hammer drivers, but may be used in many applications requiring precision pulse widths. • Four Precision Digital Time Delays • Schmitt Trigger Clock Conditioning • NPN Bipolar Output Drivers • Timing Disable Capability Using Inhibit Output • Positive or Negative Edge Strobing on the Inputs • Synchronous Polynomial Counters Used for Delay Counting MAXIMUM RATINGS* (Voltages Referenced to VSS) Rating Symbol Value Unit DC Supply Voltage MC14415FL, FP,DW MC14415VL, VP VDD – 0.5 to + 18.0 – 0.5 to + 6.0 V Input or Output Voltage (DC or Transient) Vin, Vout – 0.5 to VDD + 0.5 V Input Current (DC or Transient), per Pin Iin ± 10 mA Output Current (DC or Transient), per Pin Iout ± 20 mA Power Dissipation, per Package† PD 500 mW Storage Temperature Tstg – 65 to + 150 _C Lead Temperature (8–Second Soldering) TL 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/ _C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/ _C From 100_C To 125_C BLOCK DIAGRAM OUTPUT INHIBIT 15 11 OUTPUT D CLOCK 1 OUTPUT SET 2 INPUT DISABLE 10 STROBE 1 7 STROBE 2 9 SET D 6 SET C 5 SET B 4 SET A 3 12 OUTPUT C 13 OUTPUT B 14 OUTPUT A VDD = PIN 16 VSS = PIN 8 INPUT LOGIC DIVIDE–BY– 100 COUNTERS OUTPUT BUFFERS COMMON LOGIC CLOCK CONDITIONING CIRCUIT MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1995 REV 3 1/94 MC14415 L SUFFIX CERAMIC CASE 620 ORDERING INFORMATION MC14415FP (3.0 V–18 V) Plastic MC14415VP (3.0 V–6.0 V) Plastic MC14415FL (3.0 V–18 V) Ceramic MC14415VL (3.0 V–6.0 V) Ceramic MC14415DW (3.0 V–18 V) SOIC TA = – 55° to 125°C for all packages.
