The TC74VHCT125A/126A are high speed CMOS QUAD BUS
BUFFERs fabricated with silicon gate C²MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Shottky TTL while maintaining the CMOS low power
dissipation.
The TC74VHCT125A requires the 3-state control input G to
be set high to place the output into the high impedance state,
whereas the TC74VHCT126A requires the control input G to be
set low to place the output into high impedance.
The input voltage are compatible with TTL output voltage.
This device 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. There structure prevents device detsruction
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: tpd = 3.8 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• Compatible with TTL inputs: 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 = 0.8 V (max)
• Pin and function compatible with the 74 series
(74AC/HC/F/ALS/LS etc.) 125/126 types.
