Surface Mount Optically
Coupled Isolator
HCC240, HCC242 (TX, TXV, ESA-XN)
Features:
Surface mountable on ceramic or printed circuit board
Miniature package saves circuit board area
Electrical performance similar to 4N22A and 4N24A
Hermetically sealed
Screened per MIL-PRF-19500 TX and TXV equivalent levels or
per ESA 5000
Description:
The HCC240 and HCC242 are optically coupled isolators, consisting of a gallium aluminum arsenide LED and a silicon
phototransistor mounted and coupled in a miniature surface mount hermetic leadless chip carrier. The HCC240 and HCC242
are identical except for the DC current transfer ratio. Electrical parameters are similar to the JEDEC registered 4N22A and
4N24A. These solid state couplers are ideal for designs where board space and device weight are important design
considerations. Typical screening and lot acceptance tests are provided on page 13-4. The burn-in condition is VCE = 9 V, PD
= 275 mW, IF = 20-50 mA (adjusted to achieve PD). No HTRB is performed on this device.
