TC74VCX16646FT
Low-Voltage 16-Bit Bus Transceiver/Register with 3.6-V Tolerant Inputs and Outputs
The TC74VCX16646FT is a high-performance CMOS 16-bit bus
transceiver/register. 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.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
This device is bus transceiver with 3-state outputs, D-type
flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the internal registers.
All inputs are equipped with protection circuits against static
discharge.
Weight: 0.25 g (typ.)
Features (Note)
• Low-voltage operation: V_CC = 1.8 to 3.6 V
• High-speed operation: t_pd = 2.9 ns (max) (V_CC = 3.0 to 3.6 V)
: t_pd = 3.5 ns (max) (V_CC = 2.3 to 2.7 V)
: t_pd = 7.0 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
• Bidirectional interface between 2.5 V and 3.3 V signals.
• 3.6-V tolerant function and power-down protection provided on all inputs and outputs
Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down resistors.
