TC7MH367FK,TC7MH368FK
HEX Bus Buffer
TC7MH367FK Non-Inverted, 3-State Outputs
TC7MH368FK Inverted, 3-State Outputs
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 7 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.

Note2: 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)
