TC74VCXH16244FT
Low-Voltage 16-Bit Bus Buffer with Bushold
The TC74VCXH16244FT is a high-performance CMOS 16-bit
bus buffer. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it
achieves high-speed operation while maintaining the CMOS low
power dissipation.
This device is non-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 be used with 3-state memory address drivers, etc.
The A data inputs include active bushold circuitry, eliminating
the need for external pull-up resistors to hold unused or floating

data inputs at a valid logic level.
All inputs are equipped with protection circuits against static discharge.
Features
• Low-voltage operation: V_CC = 1.8 to 3.6 V
• Bushold on data inputs eliminating the need for external pull-up/pull-down resistors
• High-speed operation: t_pd = 2.5 ns (max) (V_CC = 3.0 to 3.6 V)
: t_pd = 3.0 ns (max) (V_CC = 2.3 to 2.7 V)
: t_pd = 5.0 ns (max) (V_CC = 1.8 V)
• Output current: I_OH/I_OL = ±24 mA (min) (V_CC = 3.0 V)
: I_OH/I_OL = ±18 mA (min) (V_CC = 2.3 V)
: I_OH/I_OL = ±6 mA (min) (V_CC = 1.8 V)
• Latch-up performance: −300 mA
• ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
• Package: TSSOP
• 3.6-V tolerant function and power-down protection control inputs and outputs
