TI CD74HC4520M96

The CD74HC4518 is a dual BCD up-counter. The ’HC4520 and CD74HCT4520 are dual binary up-counters. Each device consists of two independent internally synchronous 4-stage counters. The counter stages are D-type flip-flops

• High-Speed CMOS Logic Dual Synchronous Counters having interchangeable CLOCK and ENABLE lines for incrementing on either the positive-going or the negativegoing transition of CLOCK.
• The counters are cleared by high levels on the MASTER RESET lines.
• The counter can be cascaded in the ripple mode by connecting Q₃ to the ENABLE input of the subsequent counter while the CLOCK input of the latter is held low.
• 2V to 6V Operation
• High Noise Immunity: Nₗₗ = 30%, N₁ₕ = 30% of Vcc at Vcc = 5V
• 4.5V to 5.5V Operation
• Direct LSTTL Input Logic Compatibility, Vₗₗ = 0.8V (Max), Vₕₕ = 2V (Min)
• CMOS Input Compatibility, Iₗ ≤ 1μA at V₀ₗ, V₀ₕ
