Dual supply translating transceiver; auto direction sensing; 3-state
[1] V
CCI
is the supply voltage associated with the input.
[2] For measuring data rate, pulse width, propagation delay and output rise and fall measurements, R
L
= 1 M; for measuring enable and
disable times, R
L
= 50 k.
[3] V
CCO
is the supply voltage associated with the output.
Test data is given in Table 15
.
All input pulses are supplied by generators having the following characteristics: PRR 10 MHz; Z
O
= 50 ; dV/dt 1.0 V/ns.
R
L
= Load resistance.
C
L
= Load capacitance including jig and probe capacitance.
V
EXT
= External voltage for measuring switching times.
