CONDITIONS
RL = 10 kâ¦; CL = 50 pF
(see Fig.14)
RL = 10 kâ¦; CL = 50 pF
(see Fig.14)
RL = 600 â¦; CL = 50 pF
(see Figs 12 and 15)
RL = 600 â¦; CL = 50 pF;
f = 1 MHz (E or Sn,
square-wave between
VCC and GND,
tr = tf = 6 ns)
(see Fig.16)
RL = 50 â¦; CL = 10 pF
(see Fig.13 and 14)
Notes to AC characteristics
1. Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 â¦).
2. Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 â¦).
General note
Vis is the input voltage at a Yn or Z terminal, whichever is assigned as an input.
Vos is the output voltage at a Yn or Z terminal, whichever is assigned as an output.
Test conditions:
VCC = 4.5 V; GND = 0 V; VEE = â4.5 V;
RL = 50 â¦; Rsource = 1 kâ¦
