General Description
The EL4332C is a triple very high speed 2:1 Multiplexer-Amplifier. It
is intended primarily for component video multiplexing and is espe-
cially suited for pixel switching. The amplifiers have their gain set to 2
internally, which reduces the need for many external components. The
gain-of-2 facilitates driving back terminated cables. All three amplifi-
ers are switched simultaneously from their A to B inputs by the
TTL/CMOS compatible, common A/B control pin.
A -3 dB bandwidth of 300 MHz together with 3 ns multiplexing time
enable the full performance of the fastest component video systems to
be realized.
The EL4332C runs from standard ±5V supplies, and is available in the
narrow 16-pin small outline package.

used, a 220Ω to 330Ω resistor to the -5.2V rail would
have the same effect.
Expanding the Multiplexer
In Figure 4, a 3:1 multiplexer circuit is shown. The
expansion to more inputs is very straight forward. Since
the EL4332C has a fixed gain of 2, interstage attenuators
may be required as shown in Figure 3. The truth table for
the 3:1 multiplexer select lines is:

Mux Output
R3, G3, B3
R2, G2, B2
R1, G1, B1
When interstage attenuators are used, the values should
be kept down in the region of 50Ω–300Ω. This is to pre-
vent a combination of circuit board stray capacitance
and the EL4332C’s input capacitance forming a signifi-
cant pole. For example, if instead of 100Ω as shown,
resistors of 1 kΩ had been used, and assuming 3 pF of
stray and 3 pF of input capacitance, a pole would be
formed at about 53 MHz.
