32 x 16 Nonblocking Video Crosspoint Switch

SWITCHING CHARACTERISTICS
((VCC - VEE) = +4.5V to +10.5V, VDD = +2.7V to +5.5V, DGND = AGND = 0, VIN_ = 0 for dual supplies, VIN_ = +1.75V for single sup-
ply, RL = 150Ω to AGND, CL = 100pF, AV = +1V/V, and TA = TMIN - TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: Associated output voltage may be determined by multiplying the input voltage by the specified gain (AV) and adding output
offset voltage.
Note 2: Logic-level characteristics apply to the following pins: DIN, DOUT, SCLK, CE, UPDATE, RESET, A3–A0, MODE, and AOUT.
Note 3: Switching transient settling time is guaranteed by the settling time (tS) specification. Switching transient is a result of updat-
ing the switch matrix.
Note 4: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0 to 100IRE). IRE is a unit of
video-signal amplitude developed by the International Radio Engineers: 140IRE = 1.0V.
Note 5: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.
