It is designed specifically to be compatible with IEEE Std 1194.1-1991. The B port operates at BTL-signal levels. The open-collector B ports are specified to sink 100 mA and have minimum output edge rates of 2 ns. Two output enables (OEB and OEB) are provided for the B outputs. When OEB is low, OEB is high, or VCC is less than 2.1 V, the B port is turned off. Copyright © 1999, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
