Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.1 μF be connected from pin 6 to pin 7 of the receiver. Total lead length between both ends of the ca-
pacitor and the pins should not exceed 20 mm.
3. Pins 1 and 4 are electrically connected to the metal housing and are also used for mounting and retaining purposes. It is required that pin 1
and 4 be connected to ground to maintain metal housing shield e ectiveness.
4. Moisture sensitivity level (MSL) is 3.
HFBR-2505CFZ Receiver
The HFBR-2505CFZ receiver includes a monolithic DC
coupled, digital IC receiver with open collector Schottky
output transistor. An internal pullup resistor to V
CC
is
available at pin 5. The optical port is compatible with SMA
connectors. The speci ed signal rate of HFBR-2505CFZ
is 2 MBd.
