They have the same high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The M54/74HCT160/162 are BCD Decade counters and the M54/74HCT161/163 are 4 bit binary counters. The CLOCK input is active on the rising edge. Both LOAD and CLEAR inputs are active Low. Presetting of all four IC’s is synchronous on the rising edge of the CLOCK. The function on the M54/74HCT162/163 is synchronous to CLOCK, while the M54/74HCT160/161 counters are cleared asynchronously. Two enable inputs (TE and PE) and CARRY output are provided to enable easycascading of counters, which facilities easy implementation of N-bit counters without using external gates. This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption. All inputs are equipped with ORDER CODES : M54HCTXXXF1R M74HCTXXXM1R M74HCTXXXB1R M74HCTXXXC1R PIN CONNECTIONS (top view) NC = No Internal Con- October 1993 1/16 M54/M74HCT160/161/162/163 I NPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No 1 2 3, 4, 5, 6 7 10 9 14, 13, 12, 11 15 8 16 SYMBOL CLEAR CLOCK A, B, C, D ENABLE P ENABLET LOAD QA to QD CARRY OUTPUT GND VCC NAME AND FUNCTION Master Reset Clock Input (LOW to HIGH, Edge-triggered) Data Inputs Count Enable Input Count Enable Carry Input Parallel Enable Input Flip Flop Outputs Terminal Count Output Ground (0V) Positive Supply Voltage IEC LOGIC SYMBOL (HCT160) IEC LOGIC SYMBOL (HCT161) IEC LOGIC SYMBOL (HCT162) IEC LOGIC SYMBOL (HCT163) 2/16 M54/M74HCT160/161/162/163 T RUTH TABLE M54/74HCT160/161 CLR L H H H H H Note: M54/74HCT162/163 CK X CLR L H H H H X INPUTS LD PE TE X L H H H X X X X L H X X X L X H X CK QA L A INPUTS LD PE TE X L H H H X X X X L H X X X L X H X OUTPUTS QB L QC L QD L D FUNCTION RESET TO ”0” PRESET DATA NO COUNT NO COUNT COUNT NO COUNT B C NO CHANGE NO CHANGE COUNT UP NO CHANGE X : Don’t Care A, B, C, D : Logi level of data inputs Carry : CARRY = TE • QA • QB • QC • QD ............
