Notes on Telecom Bus Output Timing:

1. Output propagation delay time is the time in nanoseconds from the 1.4 Volt

point of the reference signal to the 1.4 Volt point of the output.

2. Maximum and minimum output propagation delays are measured with a 100

pF load on all the outputs.

3. Output tristate delay is the time in nanoseconds from the 1.4 Volt point of the

reference signal to the point where the total current delivered through the

output is less than or equal to the leakage current.

4. The propagation delay, tPTEL, should be used when Telecom bus outputs are

always driven as configured by LADDOE in register. The propagation delays,

tPTELOE and tZTEL, should be used when the Telecom bus outputs are

multiplexed with other TEMAP-84 devices using the tristate capability of the
