Description
TC74LCX16240FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74LCX16240FT
Low-Voltage 16-Bit Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs
The TC74LCX16240FT is a high-performance CMOS 16-bit bus
buffer. Designed for use in 2.5-V or 3.3-V systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
The device is designed for low-voltage (2.5-V or 3.3-V ) VCC
applications, but it could be used to interface to 5-V supply
environment for both inputs and outputs.
This device is inverting 3-state buffer having four active-low
output enables. It can be used as four 4-bit buffers two 8-bit
buffers or one 16-bit buffer. When the OE input is high, the outputs are in a high-impedance state. This device is designed to
Weight: 0.25 g (typ.)
be used with 3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static discharge.
Features
Low-voltage operation: VCC = 2.0 to 3.6 V High-speed operation: tpd = 4.5 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 Package: TSSOP Power-down protection provided on all inputs and outputs
