54FCT245 Octal Bidirectional Transceiver with TRI-STATE® Outputs General Description The ’FCT245 contains eight non-inverting bidirectional buff- ers 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 trans- ceiver. 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 Package Package Description Number 54FCT245DMQB J20A 20-Lead Ceramic Dual-In-Line 54FCT245FMQB W20A 20-Lead Cerpak 54FCT245LMQB E20A 20-Lead Ceramic Leadless Chip Carrier, Type C Logic Symbol TRI-STATE® is a registered trademark of National Semiconductor Corporation.
