Automotive 125 °C Analog Switch
Dual DPDT / Quad SPDT, 0.37 , 338 MHz Bandwidth
DESCRIPTION
FEATURES
The DGQ2788A, is a four-channel single-pole double-throw
(SPDT) analog switch with two control inputs. It is also
known as a two-channel double-pole double-throw (DPDT)
configuration. The part is designed to operate from 1.8 V to
5.5 V single power rail. All switches conduct equally well in
both directions, offering rail to rail signal switching and can
be used both as multiplexers as well as de-multiplexers.
• 1.8 V to 5.5 V single supply operation
• Low resistance: 0.37 /typ. at 2.7 V
• Highly flat and matched RON
• Low parasitic capacitance,
CON = 26 pF, COFF = 14.5 pF
• High bandwidth: 338 MHz
• 0.1 ns/typ. propagation delay for rail to rail fast
edge pulsing signal
The DGQ2788A offers low parasitic capacitance and highly
matched low and flat switch resistance over the full signal
range. It features break-before-make switching and low
control logic threshold. The part supports rail to rail fast
edge pulsing signals and have 0.1 ns/typ. propagation
delay. It is ideal for both analog and digital signal switching
in space constrain applications requiring high performance
and efficient use of board space.
• Guaranteed logic high 1.2 V, logic low 0.3 V
• Break before make switching
• Signal swing over V+ capable
• Power down protection
• Latch up current: 300 mA (JESD78)
• Material categorization: for definitions of compliance
