The TC7MH367FK and TC7MH368FK are advanced high
speed CMOS HEX bus buffers fabricated with silicon gate
C2MOS technology.
They achieve the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
They contain six buffers; four buffers are controlled by an
enable input (G1), and the other two buffers are controlled by
another enable input (G2). The outputs of each buffer group are
Weight: 0.02 g (typ.)
enabled when G1 and/or G2 inputs are held low; if held high,
these outputs are in a high impedance state.
The TC7MH367FK is a non-inverting output type, while the TC7MH368FK is an inverting output type.
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).

(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/6 (per bit)
