TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MH595FK
8-Bit Shift Register/Latch (3-State)
The TC7MH595FK is an advanced high speed 8 bit shift
2
register/latch fabricated with silicon gate C MOS technology.
It achieves the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
The TC7MH595FK contains an 8 bit static shift register which
feeds an 8 bit storage register.
Shift operation is accomplished on the positive going transition
of the SCK input. The output register is loaded with the contents
of the shift register on the positive going transition of the RCK
input. Since RCK and SCK signals are independent, parallel
outputs can be held stable during the shift operation. And, since
the parallel outputs are 3-state, it can be directly connected to 8
bit bus. This register can be used in serial-to-parallel conversion,
data receivers, etc.
Weight: 0.02 g (typ.)
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
