Fairchild Semiconductor H21LOB

The H21L series are slotted optical switches designed for multipurpose non contact sensing. They consist of a GaAs LED and a silicon OPTOLOGIC®. The output is either inverting or non-inverting, with a choice of totem-pole or open-collector configuration for TTL/CMOS compatibility FEATURES • Low cost • 0.035” apertures • Black plastic opaque housing • Mounting tabs on housing • Choice of inverter or buffer output functions • Choice of open-collector or totem-pole output configuration • TTL/CMOS compatible output functions 2001 Fairchild Semiconductor Corporation DS300294 5/29/01 1 OF 8 OPTOLOGIC® OPTICAL INTERRUPTER SWITCH H21LTB SCHEMATICS H21LTI H21LOB H21LOI ANODE (1) VOLTAGE REGULATOR VCC (3) H21LTB LA VOUT (4) Totem-Pole Output...
