SYNCHRONOUS PRESETTABLE BCD DECADE COUNTER The MC74AC160/74ACT160 and MC74AC162/74ACT162 are high-speed synchronous decade counters operating in the BCD (8421) sequence. They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters. The MC74AC160/74ACT160 has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW. The MC74AC162/74ACT162 has a Synchronous Reset input that overrides counting and parallel loading and allows all outputs to be simultaneously reset on the rising edge of the clock. • • • • • N SUFFIX CASE 648-08 PLASTIC Synchronous Counting and Loading High-Speed Synchronous Expansion Typical Count Rate of 120 MHz Outputs Source/Sink 24 mA ′ACT160 and ′ACT162 Have TTL Compatible Inputs VCC 16 TC Q0 14 Q1 13 Q2 12 Q3 11 CET PE 15 10 9 1 2 3 4 5 6 7 8 *R CP P0 P1 P2 P3 CEP GND D SUFFIX CASE 751B-05 PLASTIC LOGIC SYMBOL PE P0 P1 P2 P3 CEP CET TC CP *R Q0 Q1 Q2 Q3 PIN NAMES CEP CET CP MR SR P0–P3 PE Q0–Q3 TC Count Enable Parallel Input Count Enable Trickle Input Clock Pulse Input (′160) Asynchronous Master Reset Input (′162) Synchronous Reset Input Parallel Data Inputs Parallel Enable Input Flip-Flop Outputs Terminal Count Output *MR for ′160 *SR for ′162 FACT DATA 5-1 MC74AC160 MC74ACT160 MC74AC162 MC74ACT162 FUNCTIONAL DESCRIPTION The MC74AC160/74ACT160 and MC74AC162/74ACT162 count modulo-10 in the BCD (8421) sequence. From state 9 (HLLH) they increment to state 0 (LLLL). The clock inputs of all flip-flops are driven in parallel through a clock buffer. Thus all changes of the Q outputs (except due to Master Reset of the ′160) occur as a result of, and synchronous with, the LOW-to-HIGH transition of the CP input signal. The circuits have four fundamental modes of operation, in order of precedence: asynchronous reset (′160), synchronous reset (′162), parallel load, count-up and hold. Five control inputs — Master Reset (MR, ′160), Synchronous Reset (SR,′162), Parallel Enable (PE), Count Enable Parallel (CEP) and Count Enable Trickle (CET) — determine the mode of operation, as shown in the Mode Select Table. A LOW signal on MR overrides all other inputs and asynchronously forces all outputs LOW. A LOW signal on SR overrides counting and parallel loading and allows all outputs to go LOW on the next rising edge of CP. A LOW signal on PE overrides counting and allows information on the Parallel Data (Pn) inputs to be loaded into the flip-flops on the next rising edge of CP. With PE and MR (′160) or SR (′162) HIGH, CEP and CET permit counting when both are HIGH. Conversely, a LOW signal on either CEP or CET inhibits counting. The MC74AC160/74ACT160 and MC74AC162/74ACT162 use D-type edge-triggered flip-flops and changing the SR, PE, CEP and CET inputs when the CP is in either state does not cause errors, provided that the recommended setup and hold times, with respect to the rising edge of CP, are observed. The Terminal Count (TC) output is HIGH when CET is HIGH and counter is in state 9. To implement synchronous multistage counters, the TC outputs can be used with the CEP and CET inputs in two different ways. Please refer to the MC74AC568 data sheet. The TC output is subject to decoding spikes due to internal race conditions and is therefore not recommended for use as a clock or asynchronous reset for flip-flops, counters or registers. In the MC74AC160/74ACT160 and MC74AC162/74ACT162 decade counters, the TC output is fully decoded and can only be HIGH in state 9. If a decade counter is preset to an illegal state, or assumes an illegal state when power is applied, it will return to the normal sequence within two counts, as shown in the State Diagram.
