TC74VCX541FK
1. Functional Description
• Low-Voltage Octal Bus Buffer with 3.6-V Tolerant Inputs and Outputs
2. General
The TC74VCX541FK is a high performance CMOS octal bus buffer which is guaranteed to operate from 1.2 V to
3.6 V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaing
the CMOS low power dissipation.
It is also designed with over voltage tolerant inputs and outputs up to 3.6 V.
The device is a non-inverting 3-state buffer having two active-low output enables. When either OE1 or OE2 are
high, the terminal outputs are in the high-impedance state. This device is designed to be used with 3-state memory
address drivers, etc.
All inputs are equipped with protection circuits against static discharge.
3. Features
(1) Low-voltage operation: VCC = 1.2 to 3.6 V
(2) High-speed operation: tpd = 3.5 ns (max) (VCC = 3.0 to 3.6 V)
tpd = 4.2 ns (max) (VCC = 2.3 to 2.7 V)
tpd = 8.4 ns (max) (VCC = 1.65 to 1.95 V)
tpd = 16.8 ns (max) (VCC = 1.4 to 1.6 V)
tpd = 42.0 ns (max) (VCC = 1.2 V)
(3) Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V)
IOH/IOL = ±18 mA (min) (VCC = 2.3 V)
IOH/IOL = ±6 mA (min) (VCC = 1.65 V)
IOH/IOL = ±2 mA (min) (VCC = 1.4 V)
(4) Latch-up performance: -300 mA
(5) ESD performance: Human Body Model ≥ ±2000 V
(6) 3.6 V tolerant function and power-down protection provided on all inputs and outputs.
