CD4521BE General Description

CD4521B consists of an oscillator section and 24 ripple-carry binary counter stages. The oscillator configuration (using IN1) allows design of either RC or crystal oscillator circuits. IN1 should be tied either HIGH or LOW when not in use. A HIGH on the RESET causes the counter to go to the all-0s state and disables the oscillator. The count is advanced on the negative transition of IN1 (and IN2). A time-saving test mode is described in the Functional Test Sequence Table and in Fig. 6.

The CD4521B types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Key Features

Reset disables the RC oscillator for low-power standby condition
V_DD’ and V_SS’ pins are brought out from the crystal oscillator to allow use of external resistors for low-power operation
Maximum input current of 1 µA at 18 V over full package-temperature range:
100 nA at 18 V and 25°C
Common reset
100% tested for 20-V quiescent current
5, 10 and 15 V parametric ratings
Standardized symmetrical output characteristics
Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"

Already the 2nd time i order, all the norms. I used for arduino, for a intercom copier such a screen.

S**a 12/08/2023

50A looks but for my opinion it is aprox 16-10 ampere. not burning but very very much heating on 12 amper continously , I make it parallel 2 pcs ok it is works normally

A**n 11/26/2023

As descripted . More when I use the thermoelectric peltier devices .

L**m 05/20/2021

The product meets with the description. Very fast delivery. I strongly recommend this seller.
