| MIL-STD-1553 SINGLE AND DUAL-CHANNEL 5-VOLT TRANSCEIVERS FC15539 Series The FC15539 is a complete data bus transmitter and receiver hybrid, driven from a single 5V supply (12V and 15V also available). The device conforms to MILSTD-1553B, and is screened to the requirements of MIL-STD-883, BS9450 (CECC 63000) and MIL-PRF-38534 Class H (Military) or Class K (Space) as required. Single rail operation Low power dissipation Third-order balanced receiver input filtering Enhanced input logic tracking and fault protection Short circuit protection of transmitter outputs Available in DIL or flat-pack (surface mount) Receiver output logic options for encoder/decoder compatibilty ITAR free - UK design and manufacture *CASE *GND *GND VCC (9) (7, 16) (31, 22) (33, 24) NRX DISABLE (6, 15) 3 RXDATAIN (29, 20) 9 18 20 8 RXLOGICOUT (5, 14) 15 7 NRXDATAIN (30, 21) 16 BALANCED FILTER SIGNAL LIMITING BALANCED COMPARATOR STAGE OUTPUT LOGIC DRIVERS 10 NRXLOGICOUT (8, 17) INHIBIT GENERATOR 21 TXINHIBIT (34, 25) TXDATAOUT (1, 10) 1 PULSE SHAPING 22 TXLOGICIN (35, 26) NTXDATA OUT (2, 11) 2 OUTPUT CURRENT DRIVERS PULSE OVERDURATION TIMER INPUT LOGIC DECODER 23 NTXLOGICIN (36, 27) x = pin number (Single channel) (A, B) = pin numbers (Dual channel) A .. channel A B .. channel B * 'GND' and 'CASE' pins must be connected together externally No Connection to Pins: 4,5,6,11,12,13,14,17,19,24 (Single channel) 3,4,12,13,18,19,23,28,32 (Dual channel) www.cmac.com Pin Configuration Single Channel Pin no. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Function TXDATAOUT NTXDATAOUT CASE n.c. n.c. n.c.
