54FCT245 Octal Bidirectional Transceiver with TRI-STATE Outputs August 1998 54FCT245 Octal Bidirectional Transceiver with TRI-STATE ® Outputs General Description The ’FCT245 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. Features n TTL input and output level compatible n A and B output sink capability of 48 mA, source capability of 12 mA n CMOS power consumption n Standard Microcircuit Drawing (SMD) 5962-8762901 Ordering Code: Military 54FCT245DMQB 54FCT245FMQB 54FCT245LMQB Package Number J20A W20A E20A 20-Lead Ceramic Dual-In-Line 20-Lead Cerpak 20-Lead Ceramic Leadless Chip Carrier, Type C Package Description Logic Symbol DS100950-1 TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 1998 National Semiconductor Corporation DS100950 www.national.com Free Datasheet http://www.Datasheet4U.com Connection Diagrams Pin Assignment for DIP and Flatpak.
