CD4024BE 7-stage ripple-carry binary counter/divider, 3 ... 18 V, DIL-14

CMOS 7-Stage Ripple-Carry Binary Counter/Divider

Description CD4020B, CD4024B, and CD4040B are ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered. The CD4024B types are supplied in 14-lead hermetic dual-in-line ceramic packages (F3A suffix), 14-lead dual-in-line plastic packages (E suffix), 14-lead small-outline packages (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline packages (PW and PWR suffixes).

Features - Medium-speed operation - Fully static operation - Buffered inputs and outputs - 100% tested for quiescent current at 20 V - Standardized, symmetrical output characteristics - Fully static operation - Common reset - 5-V, 10-V, and 15-V parametric ratings - Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C - Noise margin (over full package-temperature range): - 1 V at VDD = 5 V - 2 V at VDD = 10 V - 2.5 V at VDD = 15 V - Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"

Applications: - Control counters - Timers - Frequency dividers - Time-delay circuits
