feature a normal HIGH level (VOH) and a cutoff LOW level - when LOW, the outputs go to - 2.0 V and the output emitter-follower is “off”, presenting a high impedance to the bus. The bus outputs also feature edge slow-down capacitors. Both drive and receive sides feature the same logic, including a loopback path to hold data. The HOLD/LOAD function is controlled by Transmit Enable (TEN) and Receive Enable (REN) on the transmit and receive sides respectively, with a HIGH selecting LOAD. Note that the implementation of the E337 Receive Enable differs from that of the E336. A synchronous bus enable (SBUSEN) is provided for normal, non-scan operation. The asynchronous bus disable (ABUSDIS) disables the...
