Description
SOT323-5 (SC70-5L)
(W8)
The STCL132K silicon oscillator devices are reliable, easy to use, 5-pin low-cost silicon oscillators
developed primarily for microprocessor clock applications, display drivers or other system applications
where tighter clock accuracy is not critical. Compared to crystal oscillators, silicon oscillators offer the
advantages of faster startup, smaller size and improved immunity to shock, vibration and EMI.
The STCL132K silicon oscillator devices are equipped with chip enable input, offering an easy way to
stop microprocessor clocking during a power saving mode while at the same time significantly reducing
the oscillator current consumption.
