www.ti.com FEATURES SN751730 TRIPLE LINE DRIVER/RECEIVER SLLS062E – MAY 1990 – REVISED AUGUST 2007 1 • Meets or Exceeds the Requirements of IBM® 360/370 Input/Output Interface Specification for 4.5-Mb/s Operation • Single 5-V Supply • Uncommitted Emitter-Follower Output Structure for Party-Line Operation • Driver Output Short-Circuit Protection • Driver Input/Receiver Output Compatible With TTL • Receiver Input Resistance . . . 7.4 kΩ to 20 kΩ • Ratio Specification for Propagation Delay Time, Low to High/High to Low 2 DESCRIPTION/ ORDERING INFORMATION The SN751730 triple line driver/receiver is specifically designed to meet the input/output interface specifications for IBM System 360/370. It also is compatible with standard TTL logic and supply voltage levels. The low-impedance emitter-follower driver outputs of the SN751730 drive terminated lines, such as coaxial cable or twisted pair. Having the outputs uncommitted allows wired-OR logic to be performed in party-line applications. Output short-circuit protection is provided by an internal clamping network that turns on when the output voltage drops below approximately 2.5 V. An open line affects the receiver input as does a low-level input voltage. All the driver inputs and receiver outputs are in conventional TTL configuration and the gating can be used during power-up and power-down sequences to ensure that no noise is introduced to the line by pulling either DE1 or DE2 to a low level.
