VM/8-4x1 MULTIPLEXERS
VM/32K DISCRETE RELAYS
This module has 32 two pole relays arranged as eight sepa-
This module has 32 single pole single throw reed relays with
all contacts wired out separately to two 34 pin Header connectors as shown in Fig.2.
It is available with either Type S or Type M reed relays.
Insertion Loss is less than 0.1dB at 1 MHz.
Crosstalk is less than 60dB at 200 KHz.
DC Isolation is greater than 1010 ohms.
rate 4x1 multiplexers as shown in Fig.1. The 32 pairs of
inputs are brought out to two 34 pin header connectors and
the 8 pairs of outputs with the submultiplex relay are brought
out to a 20 pin header connector.
The multiplexers are available with either Type S, M or LT
relays and can be supplied in the following configurations.
Multiplexers
Multipole
8 - 4x1 two pole
4 - 4x1 four pole
4 - 8x1 two pole
2 - 4x1 eight pole
2 - 16x1 two pole
1 - 4x1 sixteen pole
1 - 32x1 two pole
1 - 64x1 single pole using submultiplexer
Bandpass of each 4x1 Mux exceeds 200 MHz which is reduced when combined in the larger Multiplexers.
Isolation is 40dB at 10 MHz with 50 ohm terminations.

VM/24DRV RELAY DRIVER MODULE
This module has 24 open collector relay drive circuits with
diode suppression and current drive capability of 1.8 amp
DC. Relay power source can be from the +5 volt or +12 volt
supplies on the VME or VXI Chassis backplane or from an
external source of up to +50 volts.
There are four driver channels per driver IC with a maximum
package dissipation of 3.8 watts at 25oC.
The drives can be wired to relays mounted on a blank area of
the circuit board or to three 20 pin connectors on the back
panel.
