1 / 8 page MOTOROLA CMOS LOGIC DATA 1 MC14566B Industrial Time Base Generator The MC14566B industrial time base generator is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. This device consists of a divide–by–10 ripple counter and a divide–by–5 or divide–by–6 ripple counter to permit stable time generation from a 50 or 60 Hz line. By cascading this device as divide–by–60 counters, seconds and minutes can be counted and are available in BCD format at the circuit outputs. An internal monostable multivibrator is included whose output can be used as a reset or clock pulse providing additional frequency flexibility. Also a pin has been included to allow divide–by–5 counting for generating 1.0 Hz from European 50 Hz line. Pin 11 = VDD will cause ÷ 5. • Negative Edge Triggered Counters for Ease of Cascading • Pulse Shapers on Counter Inputs Accept Slow Input Rise Times • Monostable Multivibrator Positive or Negative Edge Triggered • Diode Protection on All Inputs • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V Iin, Iout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 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 CA ÷10 RESET ÷5/÷6 CONTROL CB ÷5/÷6 B A BCD OUT BCD OUT Qm 10 1 2 11 15 7 9 PULSE SHAPER PULSE SHAPER MONO– STABLE MULTI– VIBRATOR Q0A Q1A Q2A Q3A R C R Q0B Q1B Q2B C 3 4 5 6 12 13 14 MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1995 REV 3 1/94 MC14566B L SUFFIX CERAMIC CASE 620 ORDERING INFORMATION MC14XXXBCP Plastic MC14XXXBCL Ceramic MC14XXXBD SOIC TA = – 55° to 125°C for all packages.
