(see Fig.14)
R_L = 10 kΩ; C_L = 50 pF
(see Fig.14)
R_L = 600 Ω; C_L = 50 pF
(see Figs 12 and 15)
R_L = 600 Ω; C_L = 50 pF;
f = 1 MHz (E₁, E₂ or S_n,
square-wave between V_CC
and GND, t_r = t_f = 6 ns)

(see Figs 13 and 14)
Notes to AC characteristics
1. Adjust input voltage V_is to 0 dBm level (0 dBm = 1 mW into 600 Ω).
2. Adjust input voltage V_is to 0 dBm level at V_os for 1 MHz (0 dBm = 1 mW into 50 Ω).
V_is is the input voltage at a Y_n or Z terminal, whichever is assigned as an input.
V_os is the output voltage at a Y_n or Z terminal, whichever is assigned as an output.
Test conditions:
V_CC = 4.5 V; GND = 0 V; V_EE = −4.5 V;
R_L = 50 Ω; R_source = 1 kΩ.
