DESCRIPTION
The M66007 is a semiconductor integrated circuit providing
the 12-bit parallel input-serial output shift register function.
This product is completely designed with CMOS to sharply
reduce power consumption compared with bipolar or Bi-
CMOS product.
The M66007, developed as an input only expander IC neces-
sary for microcomputer periphery, is widely applicable as a
data parallel/serial conversion IC.
FEATURES
Control signals of only two pins including LE/D and CLK
Low power consumption of 50 μW/package maximum
(Vcc=5V, Ta=25°C at time of standstill)
Schmitt triggered input (LE/D, CLK, D0 to D11)
Wide operating supply voltage range (Vcc=2~6V)
Wide operating temperature range (Ta=–20~75°C)
APPLICATION
Parallel/serial data conversion for microcomputer periphery
FUNCTION
The M66007 uses a silicon gate CMOS process to achieve
low power consumption and high noise margin.
For control signals, this IC adopts only the two pins of latch
input/serial data output LE/D and clock input CLK. Each bit
of shift register of 12-bit parallel input-serial output consists of
flip-flop for shift.
When LE/D is placed in input mode, CLK is set to “H” and LE/
D changes from “H” to “L”, the status of parallel data inputs D0
to D11 at that time is latched with the flip-flop for shift and LE/
D is switched to output mode to output “L”.

After this, change of CLK from “H” to “L” makes the shift regis-
ter perform shift operation and LE/D outputs the contents of
the shift register from D0 in order.
In addition, the shift operation for up to the 12th bit is carried
out and then LE/D is switched to the input mode at the falling
edge of CLK of the 13th bit.
When power is turned on, the input/output mode of LE/D is
indeterminate. However, detection of 13 or more falling
edges of CLK sets LE/D in the input mode.
