Low Capacitance Quad 1-of-2 Multiplexer/Demultiplexer
The TC7MB3257C is a Low Capacitance CMOS Quad 1-of-2
multiplexer/demultiplexer. The low on resistance and the low
capacitance of the switch allows connections to be made with
minimal propagation delay time.
This device consists of four individual two-inputs
multiplexer/demultiplexer with common select input (S) and
output enable ( OE ). The A inputs is connected to the B1 or B2
outputs determined by the combination both the select input (S)
and output enable ( OE ). When the output enable ( OE ) input is
held “H” level, the switches are open with regardless the state of
select inputs and a high-impedance state exists between the
switches.
All inputs are equipped with protection circuits against static
discharge.
Features
Operating voltage: VCC = 4.0 to 5.5 V
On-capacitance: CI/O = 8.5 pF Switch On (typ.)@VCC=5V
On resistance: RON = 3 Ω (typ.) @VCC=4.5V, VIS=0 V
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
Compatible with TTL outputs (control inputs)
Power-down protection for inputs ( OE ,S and I/O)
Package: TSSOP16,VSSOP16 (US16) , VQON16
Pin compatible with the TC7MB3257FT/FK.
Note: When mounting VQON package, the type of recommended
flux is RA or RMA.
