TC74LCX541F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX541F, TC74LCX541FK
Low-Voltage Octal Bus Buffer with 5-V Tolerant Inputs and Outputs
The TC74LCX541 is a high-performance CMOS octal bus buffer.
Designed for use in 3.3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
The device is designed for low-voltage (3.3 V) VCC applications, but it
could be used to interface to 5 V supply environment for both inputs and
outputs.
The TC74LCX541 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.
Features
• Low-voltage operation: VCC = 1.65 to 3.6 V
• High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V)
• Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
• Latch-up performance: ≥ ±500 mA
• Available in JEITA SOP, VSSOP (US)
• Power-down protection provided on all inputs and outputs
• Pin and function compatible with the 74 series
(74AC/VHC/HC/F/ALS/LS etc.) 541 type
