Pin description
7.1 RGB switches
7.2 H-Sync/V-Sync level translator
The NX5DV713 integrates high-bandwidth SPDT switches, level-translating buffers and
level translating SPDT switches to provide a complete solution for 1-to-2 switching of VGA
signals. A select input (SEL) is used to determine which output is selected.
The NX5DV713 provides three identical single pole double throw high-bandwidth switches
to route standard VGA RGB signals (see
Table 3.
H = HIGH voltage level; L = LOW voltage level; X = Don’t care.
The horizontal and vertical synchronization buffers have inputs (H0, V0) referenced to
V
translation of synchronization signals from as low as 2.0 V up to 5.5 V and supports
low-voltage CMOS or TTL-compatible graphics controllers meeting the VESA
specification for output drive of 8 mA.
