1 / 11 page © 2005 Fairchild Semiconductor Corporation DS010945 www.fairchildsemi.com September 1991 Revised March 2005 74ABT245 Octal Bi-Directional Transceiver with 3-STATE Outputs General Description The ABT245 contains eight non-inverting bidirectional buff- ers with 3-STATE outputs and is intended for bus-oriented applications. Current sinking capability is 64 mA on both the A and B ports. The Transmit/Receive (T/R) input deter- mines 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 s Bidirectional non-inverting buffers s A and B output sink capability of 64 mA, source capability of 32 mA s Guaranteed output skew s Guaranteed multiple output switching specifications s Output switching specified for both 50 pF and 250 pF loads s Guaranteed simultaneous switching, noise level and dynamic threshold performance s Guaranteed latchup protection s High impedance glitch-free bus loading during entire power up and power down cycle s Non-destructive hot insertion capability s Disable time is less than enable time to avoid bus contention Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B. Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
