MB88346L
■ DESCRIPITON
The Fujitsu MB88346L is an 8-bit D/A converter capable of low-voltage operation, and designed with a built-in
amp on each of its 12 analog output lines for large-current drive capability.
The use of serial data input means that only three control lines are required, and enables cascade connection
of multiple MB88346L chips.
The MB88346L is suitable for applications such as electronic volume controls and replacement of semi-fixed
resistors in tuning systems.
In addition, the MB88346L is both function-compatible and pin-compatible with the MB88346B now in use,
allowing easy substitution of the MB88346L for reduced supply voltage.

■ PIN DESCRIPTION

Symbol
I/O
Function
17
DI
I
Serial address/data input to the internal 12-bit shift register: The
address/data format is that upper 4 bits (D11 to D8) indicate an
address and lower 8 bits (D7 to D0) indicate data. The D11 (MSB) is
the first-in bit and D0 (LSB) is the last-in bit.
14
DO
O
Outputs MSB bit data from 12-bit shift register.
16
CLK
I
Shift clock input to the internal 12-bit shift register: At the rising edge
of CLK data on the DI pin is shifted into the LSB of the shift register
and contents of the shift register are shifted right (to the MSB).
15
LD
I
Load strobe input for a 12-bit address/data: A high level on the LD pin
latches a 4-bit address (upper 4 bits: D11 to D8) of the internal 12-bit
shift register into the internal address decoder, and writes 8-bit data
(lower 8 bits: D7 to D0) of the shift register into an internal data latch
selected by the latched address.

WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
