1 / 10 page TLF9497 November 1994 54F74F193 UpDown Binary Counter with Separate UpDown Clocks General Description The ’F193 is an updown modulo-16 binary counter Sepa- rate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously The outputs change state synchronously with the LOW-to- HIGH transitions on the clock inputs Separate Terminal Count Up and Terminal Count Down outputs are provided that are used as the clocks for subsequent stages without extra logic thus simplifying multi-stage counter designs Individual preset inputs allow the circuit to be used as a programmable counter Both the Parallel Load (PL) and the Master Reset (MR) inputs asynchronously override the clocks Features Y Guaranteed 4000V minimum ESD protection Commercial Military Package Package Description Number 74F193PC N16E 16-Lead (0300 Wide) Molded Dual-In-Line 54F193DM (Note 2) J16A 16-Lead Ceramic Dual-In-Line 74F193SC (Note 1) M16A 16-Lead (0150 Wide) Molded Small Outline JEDEC 74F193SJ (Note 1) M16D 16-Lead (0300 Wide) Molded Small Outline EIAJ 54F193FM (Note 2) W16A 16-Lead Cerpack 54F193LM (Note 2) E20A 20-Lead Ceramic Leadless Chip Carrier Type C Note 1 Devices also available in 13 reel Use suffix e SCX and SJX Note 2 Military grade device with environmental and burn-in processing Use suffix e DMQB FMQB and LMQB Logic Symbols Connection Diagrams TLF9497 – 1 IEEEIEC TLF9497 – 4 Pin Assignment for DIP SOIC and Flatpak TLF9497 – 2 Pin Assignment for LCC TLF9497 – 3 TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation RRD-B30M75Printed in U S A |
