TC7MET374AFK
Octal D-Type Flip-Flop with 3-State Output
The TC7MET374AFK is an advanced high speed CMOS octal
flip-flop with 3-state output fabricated with silicon gate C2MOS
technology.
It achieves the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
This 8-bit D-type flip-flop is controlled by a clock input (CK)
and a output enable input (OE).
When the OE input is high, the eight outputs are in a high
impedance state.
The input voltage are compatible with TTL output voltage.
This device may be used as a level converter for interfacing 3.3
Weight: 0.03 g (typ.)
V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device
destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.
Note: VCC = 0 V

Note 1: 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).
Note 2: Output in off-state

(Note 2)
Note 1: Parameter guaranteed by design.

Note 2: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD・VCC・fIN + ICC/8 (per F/F)
And the total CPD when n pcs. of latch operate can be gained by the following equation:
CPD (total) = 14 + 11・n
