DESCRIPTION
M66009 silicon gate CMOS (complementary metal oxide
semiconductor) integrated circuit converts 8-bit data from se-
rial to parallel and vice versa.
This IC has 5 address setting bits, which enable users to set
a distinctive address.
This IC offers a wide range of applications, such as for micro-
computer input/output port extension.
FEATURES
• Has 5 bits for address setting
• Connected to microcomputer via 4 pins (EN,CLK, DI and
DO)
• Input/output setting possible by the bit
• Schmitt input (RESET, EN and CLK)
• Wide operating temperature range (Ta = –20˚C to 75˚C)
APPLICATION
Microcomputer I/O port extension, etc.
