Preset takes place regardless of the levels at count enable inputs (CEP and CET). FEATURES • Synchronous counting and loading • Two count enable inputs for n-bit cascading • Positive-edge triggered clock • Asynchronous reset A LOW level at the master reset input (MR) sets all four outputs of the flip-flops (Q0 to Q3) to LOW level regardless of the levels at CP, PE, CET and CEP inputs (thus providing an asynchronous clear function). • Output capability: standard • ICC category: MSI GENERAL DESCRIPTION The look-ahead carry simplifies serial cascading of the counters. Both count enable inputs (CEP and CET) must be HIGH to count. The CET input is fed forward to enable the terminal count output (TC). The TC output thus enabled will produce a HIGH output pulse of a duration approximately equal to a HIGH level output of Q0. This pulse can be used to enable the next cascaded stage. The 74HC/HCT160 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT160 are synchronous presettable decade counters which feature an internal look-ahead carry and can be used for high-speed counting. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset to a HIGH or LOW level. A LOW level at the parallel enable The maximum clock frequency for the cascaded counters is determined by the CP to TC propagation delay and CEP to CP set-up time, according to the following formula: 1 fmax = --------------------------------------------------------------------------------------------------------t P ( max ) ( CP to TC ) + t SU (CEP to CP) QUICK REFERENCE DATA GND = 0 V; Tamb= 25 °C; tr = tf = 6 ns Notes TYPICAL SYMBOL PARAMETER tPHL tPLH propagation delay CP to Qn CP to TC MR to Qn MR to TC CET to TC CONDITIONS CL = 15 pF; VCC = 5 V propagation delay CP to Qn CP to TC CET to TC UNIT HC HCT 19 21 21 21 14 21 24 23 26 14 ns ns ns ns ns 19 21 14 21 20 7 ns ns ns fmax maximum clock frequency 61 31 MHz CI input capacitance 3.5 3.5 pF CPD power dissipation capacitance per package 39 34 pF December 1990 notes 1 and 2 2 1.
