Philips 74F777
The 74F777 is a triple bidirectional transceiver with Open Collector B and 3–State A port output drivers. The B port output driver is designed to sink 100mA from 2 volts to minimize crosstalk and ringing on the bus. For 5 volt systems, VX is simply tied to VCC.| Part No. | 74F777 |

FEATURES
● Latching transceiver● High drive Open Collector output current with minimum output swing range of 20 to 50 ohms and is terminated on each end with a 30 to 40 ohm resistor. A latch function is provided for the A port signals. A separate output threshold clamp voltage (VX) is provided to prevent the A port output High level from exceeding future high density processor supply voltage levels. For 5 volt systems, VX is simply tied to VCC. TYPE 74F777 TYPICAL PROPAGATION DELAY 7.0ns TYPICAL SUPPLY CURRENT( TOTAL) 45mA
● Compatible with Test Mode (TM) bus specification
● Controlled output ramp
● Multiple package options
● Industrial temperature range available (–40°C to +85°C)
