TC74LCX07F,TC74LCX07FN,TC74LCX07FT
Low-Voltage HEX Buffer with 5-V Tolerant Inputs and Outputs (open drain)
The TC74LCX07F/FN/FT is a high-performance CMOS buffer.
Designed for use in 3.3-V systems, it achieves high-speed
operation while maintaining the CMOS low power dissipation.
The TC74LCX07 has high performance MOS N-channel
transistor. (open-drain outputs)
The device is designed for low-voltage (3.3 V) V
CC
applications,
but it could be used to interface to 5-V supply environment for
inputs.
All inputs are equipped with protection circuits against static
discharge.
Features
Low-voltage operation: V
CC
= 2.0 to 3.6 V
High-speed operation: t
pz
= 3.7 ns (max) (V
CC
= 3.0 to 3.6 V)
Output current: I
OL
= 24 mA (min) (V
CC
= 3.0 V)
Latch-up performance: -500 mA
Available in JEDEC SOP, JEITA SOP and TSSOP
Open-drain outputs
Power-down protection provided on all inputs and outputs
Pin and function compatible with the 74 series
(74AC/VHC/HC/F/ALS/LS etc.) 07 type
Note: xxxFN (JEDEC SOP) is not available in
Japan.
