Description

The 74ABT245CSC belongs to ABT245 family which contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus-oriented applications. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. The Output Enable input, when HIGH, disables both A and B ports by placing them in a HIGH Z condition. Current sinking capability is 64 mA on both the A and B ports. Transmit (active HIGH) enables data from A Ports to B Ports; Receive (active LOW) enables data from B Ports to A Ports.

The features of 74ABT245CSC can be summarized as (1)bidirectional non-inverting buffers; (2)A and B output sink capability of 64 mA, source capability of 32 mA; (3)guaranteed output skew; (4)guaranteed multiple output switching specifications; (5)output switching specified for both 50 pF and 250 pF loads; (6)guaranteed simultaneous switching, noise level and; (7)dynamic threshold performance; (8)guaranteed latchup protection; (9)high impedance glitch-free bus loading during entire power up and power down cycle; (10)non-destructive hot insertion capability; (11)disable time is less than enable time to avoid bus contention.

The absolute maximum ratings of 74ABT245CSC are (1)storage temperature: -65°C to -150°C; (2)ambient temperature under bias: -55°C to +125°C; (3)junction temperature under Bias: -55°C to +150°C; (4)VCC Pin Potential to Ground Pin: -0.5V to +7.0V; (5)input voltage (Note 3): -0.5V to +7.0V; (6)input current (Note 3): -30 mA to +5.0 mA; (7)voltage applied to any output, in the disabled or power-off state: -0.5V to 5.5V; in the HIGH State: -0.5V to VCC; (8)current applied to output, in LOW state (Max): twice the rated IOL (mA); (9)DC latchup source current: -500 mA; (10)over voltage latchup (I/O): 10V.
