HV57908

64-Channel 8 MHz Serial-to-Parallel Converter with Push-Pull Outputs

Features

General Description

• 5V CMOS Logic

The HV57908 is a low-voltage to high-voltage

serial-to-parallel converter with 64 push-pull outputs.

This device is designed as a driver for EL displays. It

can also be used in any application requiring

• Up to 80V Output Voltage

• Low-power Level Shifting

• 8 MHz Data Rate

multiple-output

high-voltage

low-current

• Latched Data Outputs

sourcing-and-sinking capabilities, such as driving

plasma panels, vacuum fluorescent displays and large

matrix LCD displays.

• Forward and Reverse Shifting Options (DIR pin)

• Diode to V_PPallows Efficient Power Recovery

• Outputs may be Hot Switched

The device consists of a 64-bit Shift register, 64 latches

and control logic to perform the polarity select and

blanking of the outputs. H_VOUT1 is connected to the

first stage of the first Shift register through the polarity

and blanking logic. Data is shifted through the Shift

registers on the logic low-to-high transition of the clock.

The DIR pin causes counter-clockwise shifting when

connected to GND and clockwise shifting when

connected to VDD. A data output buffer is provided for

cascading devices. This output reflects the current

status of the last bit of the Shift register, HV_OUT64. The

operation of the Shift register is not affected by the latch

enable (LE), blanking (BL) and polarity (POL) inputs.

Transfer of data from the Shift registers to the latches

occurs when the LE input is high. The data in the

latches is stored when LE is low.

Applications

• Display Driver

• Vacuum Fluorescent Display Driver

• Inkjet Driver

• 3D Printer Driver

• Microelectromechanical Systems Applications
