BU-63133L8 Datasheet | Data Device Corporation

FEATURES - World's smallest 3.3V MIL-STD-1553 Transceiver - Requires Only 3.3V Power Supply - -55°C to +125°C Operation - 32-Pad LPCC - 0.276" x 0.276" (7 X 7 mm) Body and Footprint Size - 0.039" Inch Maximum Height - Low Power Consumption - Sleep Mode Allows Further Power Reduction - Single Transceiver Allows Full Dual Redundancy DESCRIPTION The BU-63133 transceiver is a plete transmitter and receiver conforming fully to MIL-STD-1553A, 1553B, and 1760. The use of two BU-63133 transceivers provides full dual redundancy. Features include: +3.3V power supply voltage, Harris interface type, and a ultra low profile, small footprint, 32-pad Leadless Plastic Chip Carrier package (LPCC). The LPCC package provides an integral, exposed heatsink on the package bottom. This package allows 100% duty cycle operation at 125°C when the heatsink is soldered to an appropriately constructed PCB. The receiver section of the BU-63133 accepts Manchester II data from a MIL-STD-1553 Data Bus and produces TTL level signals at its outputs: RX DATA OUT and RX DATA OUT. These outputs represent positive and negative excursions of the input data signals beyond an internally fixed threshold level. An external STROBE input enables or disables the receiver's outputs. The transmitter section accepts bipolar TTL signal data at its TX DATA IN and TX DATA IN inputs and produces Manchester II data at the TX DATA OUT and TX DATA OUT outputs. When used with the remended transformers, the transmitter typically produces 21 Vp-p for transformer coupled outputs and 7 Vp-p at the bus. An external input, TX INHIBIT, takes priority over the transmitter inputs and disables the transmitter when activated with a logic "1". The ultra small size, +3.3V power supply voltage, and pli.. ance with MIL-STD-1553A, 1553B, and 1760 simplify engineering design, making it an excellent choice for interfacing with any MILSTD-1553 system.
