INTEGRATED CIRCUITS 74ABTL3205 10-bit BTL transceiver with registers Product specification 1995 Jun 16 Philips Semiconductors Philips Semiconductors 10-bit BTL transceiver with registers Product specification 74ABTL3205 FEATURES 10-bit BTL transceiver Drives heavily loaded backplanes with equivalent load impedances down to 10 ohms High drive 100mA BTL open collector drivers on B-port Allows incident wave switching in heavily loaded backplane buses Reduced BTL voltage swing produces less noise and reduces power consumption Built-in precision band-gap reference provides accurate receiver thresholds and improved noise immunity Compatible with IEEE Futurebus+ or proprietary BTL backplanes Controlled output ramp and multiple GND pins minimize ground bounce Tight output skew (0.5nsec typical) Glitch-free power up/down operation Low ICC current Supports live insertion High density packaging ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model DESCRIPTION This transceiver is a 10 bit bidirectional transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA. Precision band gap references on the B-port insure very good margins by limiting the switching threshold to a narrow region centered at 1.55V. The B-port interfaces to “Backplane Transceiver Logic” (See the IEEE 1194.1 B...
