MOTOROLA SEMICONDUCTOR TECHNICAL DATA Presettable Counters MC54/74HC160 MC54/74HC162 High–Performance Silicon–Gate CMOS The MC54/74HC160 and HC162 are identical in pinout to the LS160 and LS162, respectively. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC160 and HC162 are programmable BCD counters with asynchronous and synchronous Reset inputs, respectively. Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2 to 6 V Low Input Current: 1 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 234 FETs or 58.5 Equivalent Gates 16 1 J SUFFIX CERAMIC PACKAGE CASE 620–10 16 1 N SUFFIX PLASTIC PACKAGE CASE 648–08 16 1 D SUFFIX SOIC PACKAGE CASE 751B–05 LOGIC DIAGRAM ORDERING INFORMATION P0 PRESENT DATA INPUTS P1 P2 P3 3 4 5 6 14 13 12 11 Q0 Q1 Q2 Q3 RIPPLE CARRY OUT BCD OR BINARY OUTPUTS MC54HCXXXJ MC74HCXXXN MC74HCXXXD Ceramic Plastic SOIC PIN ASSIGNMENT RESET CLOCK P0 P1 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC RIPPLE CARRY OUT Q0 Q1 Q2 Q3 ENABLE T LOAD CLOCK 2 15 RESET LOAD COUNT ENABLES P2 P3 ENABLE P PIN 16 = VCC PIN 8 = GND GND ENABLE P ENABLE T Device HC160 HC162 Count Mode BCD BCD Reset Mode Asynchronous Synchronous FUNCTION TABLE Inputs Clock Reset* L H H H H Load X L H H H Enable P X X H L X Enab……
