H21L Series OPTOLOGIC® Optical Interrupter Switch Features Description ■ Low cost The H21L series are slotted optical switches designed for multipurpose non contact sensing. They consist of a GaAs LED and a silicon OPTOLOGIC® sensor packaged in an injection molded housing and facing each other across a .124" (3.15 mm) gap. The output is either inverting or non-inverting, with a choice of totem-pole or open-collector configuration for TTL/CMOS compatibility. ■ 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 Part Number Definitions ■ TTL/CMOS compatible output functions H21LTB, Totem-pole, buffer output H21LTI, Totem-pole, inverter output H21LOB, Open-collector, buffer output H21LOI, Open-collector, inverter output Package Dimensions 0.972 (24.7) 0.957 (24.3) Ø 0.133 (3.4) Ø 0.126 (3.2) (2X) 0.472 (12.0) 0.457 (11.6) CL 0.249 (6.35) 0.243 (6.15) + D E + CL 0.39 (1.00) 0.34 (0.85) 0.755 (19.2) 0.745 (18.9) 0.129 (3.3) 0.119 (3.0) 0.103 (2.60) NOM Optical CL 0.433 (11.0) 0.422 (10.7) 0.125 (3.2) 0.119 (3.0) 0.315 (8.0) MIN CL 0.250 (6.36) 0.216 (5.50) 0.350 (8.9) 0.330 (8.4) 0.350 (8.9) 0.330 (8.4) 0.055 (1.40) 0.045 (1.14) 2 3 1 5 0.110 (2.8) 0.091 (2.3) PIN 1 ANODE PIN 2 CATHODE PIN 3 VCC 4 PIN 4 VO 0.020 (0.51) (SQ) ©2004 Fairchild Semiconductor Corporation H21L Series Rev. 1.1.0 0.055 (1.40) 0.045 (1.14) PIN 5 GND Notes: 1.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
