General Description
The HV610 is a 32-channel high voltage, medium current
driver IC. The outputs can be either at V
PPS
, V
NN
, HiZ, or
HVGND.
Data is shifted through four parallel 8-bit shift registers on
the low to high transition of the clock. A data output buffer is
provided for cascading devices. Data is transferred to a 32-bit
latch when logic level high is applied to the LE input. The CLR
signal will reset both the shift register and the latch. Output
states are controlled by POS, and NEG input signals, and by
data in the latch. All outputs are tri-stated upon a logic high on
the HiZ input signal.
Applications
► High speed print head driver
