Q427242110002 RTC-72421B - RTC IC Dip18

Q427242110002 RTC-72421B - RTC IC, YYYY:MM:DD:Hr:Min:Secs, 12Hr / 24Hr, 4.5 V to 5.5 V, DIP, 18Pins

he Q427242110002 RTC-72421 is a Real Time Clock IC Module that can be connected directly to a microprocessors bus. Its built-in crystal unit enables highly accurate time-keeping with no physical access required for adjustment and since there is no need to connect external components and mounting. In addition to its time and calendar functions, this enables the use of 30-seconds correction and fixed-period interrupts functions.

Built-in crystal unit removes need for adjustment
Microprocessor bus compatible
Use of C-MOS IC enables low current consumption
Compatibility with Intel CPU bus
Address latch enable (ALE) pin compatible with multiplex bus CPUs
Fixed-period interrupts function
Stop, start and reset functions
