SCL

Serial Clock. The SCL input is used to clock all serial data into and out of the device. The input buffer

on this pin is always active (not gated). It is disabled when the backup power supply on the VBAT pin

is activated to minimize power consumption.

out control bits of the control/status register. Interrupt Mode. The pin provides an interrupt signal

output. This signal notifies a host processor that an alarm has occurred and requests action. It is an

open drain active low output. Frequency Output Mode. The pin outputs a clock signal, which is

It is an open drain output. The output is open drain and requires a pull-up resistor.

1. Please refer to TB347 for details on reel specifications.

2. These Intersil plastic packaged products employ special material sets, molding compounds and 100% matte tin plate plus

anneal (e3) termination finish. These products do contain Pb but they are RoHS compliant by exemption 7 (Pb in high melting

temperature type solders, electronic ceramic parts (e.g. piezoelectronic devices)) and exemption 5 (Pb in glass of electronic

components). These Intersil RoHS compliant products are compatible with both SnPb and Pb free soldering operations. These

Intersil RoHS compliant products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
