12-stage binary ripple counter
FEATURES * Output capability: standard * ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT4040 are high-speed Si-gate CMOS devices and are pin compatible with "4040" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4040 are 12-stage binary ripple counters with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve parallel outputs QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns

(Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. APPLICATIONS * Frequency dividing circuits * Time delay circuits * Control counters
TYPICAL SYMBOL tPHL/ tPLH PARAMETER propagation delay CP to Q0 Qn to Qn+1 fmax CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information". maximum clock frequency input capacitance power dissipation capacitance per package notes 1 and 2 CONDITIONS HC CL = 15 pF; VCC = 5 V 14 8 90 3.5 20 16 8 79 3.5 20 ns ns MHz pF pF HCT UNIT
