54ABT245 Octal Bidirectional Transceiver with TRI-STATE Outputs July 1998 54ABT245 Octal Bidirectional Transceiver with TRI-STATE Outputs General Description The ’ABT245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 48 mA on both the A and B ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active HIGH) enables data from A ports to B ports; Receive (active LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a High Z condition. n Guaranteed output skew n Guaranteed multiple output switching specifications n Output switching specified for both 50 pF and 250 pF loads n Guaranteed simultaneous switching, noise level and dynamic threshold performance n Guaranteed latchup protection n High impedance glitch-free bus loading during entire power up and power down cycle n Non-destructive hot insertion capability n Disable time is less than enable time to avoid bus contention n Standard Microcircuit Drawing (SMD) 5962-9214801 Features n Bidirectional non-inverting buffers n A and B output sink capability of 48 mA, source capability of 24 mA Ordering Code: Military 54ABT245J-QML 54ABT245W-QML 54ABT245E-QML Package Number J20A W20A E20A 20-Lead Ceramic Dual-In-Line 20-Lead Cerpak 20-Lead Ceramic Leadless Chip Carrier, Type C Package……
