MC54HC161A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Presettable Counters MC54/74HCT161A MC54/74HCT163A High–Performance Silicon–Gate CMOS The MC54/74HCT161A and HCT163A are identical in pinout to the LS161A and LS163A. These devices may be used as level converters for interfacing TTL or NMOS outputs to high speed CMOS inputs. The HCT161A and HCT163A are programmable 4–bit binary counters with asynchronous and synchronous reset, respectively. 16 1 J SUFFIX CERAMIC PACKAGE CASE 620–10 Output Drive Capability: 10 LSTTL Loads TTL, NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1 µA High Noise Immunity Characteristic of CMOS Devices 16 1 16 1 N SUFFIX PLASTIC PACKAGE CASE 648–08 In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 200 FETs or 50 Equivalent Gates LOGIC DIAGRAM D SUFFIX SOIC PACKAGE CASE 751B–05 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXAD 14 13 12 11 Q0 Q1 Q2 Q3 Ripple Carry Out BCD or Binary Outputs Device HCT161A HCT163A Count Mode Binary Binary Reset Mode Asynchronous Synchronous Ceramic Plastic SOIC P0 Preset Data Inputs P1 P2 P3 Clock 3 4 5 6 2 15 Pinout: 16–Lead Package (Top View) VCC RCO* 16 15 Q0 14 Q1 13 Q2 12 Q3 11 Enable T Load 10 9 Reset Load Count Enables Enable P Enable T 1 9 7 10 Pin 16 = VCC Pin 8 = GND FUNCTION TABLE Inputs Clock Reset* L H H H H Load X L H H H Enable P X X H L X Enable T X X H ...
