Octal Bus Buffer
TC7MET540AFK Inverted, 3-State Outputs
TC7MET541AFK Non-Inverted, 3-State Outputs
The TC7MET540AFK and 541AFK are advanced high speed
CMOS octal 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.
The TC7MET540AFK is an inverting type and, the
TC7MET541AFK is a non-inverting type.
When either G1 or G2 are high , the terminal outputs are in
the high-impedance state.
The input voltage are compatible with TTL output voltage.
Weight: 0.03 g (typ.)
These devices may be used as a level converter for interfacing
3.3 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: V_CC = 0 V
Features
• High speed: t_pd = 5.4 ns (typ.) (V_CC = 5 V)
• Low power dissipation: I_CC = 4 μA (max) (Ta = 25°C)
• Compatible with TTL outputs: V_IL = 0.8 V (max)
V_IH = 2.0 V (min)
• Power down protection is provided on all inputs and outputs.
• Balanced propagation delays: t_pLH ≈ t_pHL
• Low noise: V_OLP = 1.5 V (max)
• Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 540/541 type.
