DescriptionThe SN74CBT3257PWG4 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The features of the SN74CBT3257PWG4 are: (1)Functionally Equivalent to QS3257; (2)5- Switch Connection Between Two Ports; (3)TTL-Compatible Control Input Levels; (4)Package Options Include Plastic Small-Outline (D), Shrink Small-Outline (DB, DBQ), and Thin Shrink Small-Outline (PW) Packages.
The following is about the absolute maximum ratings of SN74CBT3257PWG4: (1)Supply voltage range, VCC: 0.5 V to 7 V; (2)Input voltage range, VI: 0.5 V to 7 V; (3)Continuous channel current: 128 mA; (4)Input clamp current, IIK (VI/O < 0): 50 mA; (5)Package thermal impedance, JA: D package 73°C/W, DB package 82°C/W, DBQ package 90°C/W, PW package 108°C/W; (6)Storage temperature range, Tstg: 65°C to 150°C.
The electrical characteristics of the SN74CBT3257PWG4 are: (1)VIK: -1.2V max at VC=4.5V, II=-18mA; (2)II: ±1A max at VCC=5.5V, VI=5.5V or GND; (3)ICC: 3A max at VCC=5.5V, IO=0, VI=VCC or GND; (4)ICC: 2.5mA max at VCC=5.5V, one input at 3.4V, other inputs at VCC or GND; (5)Ci: 3.5pF at VI=3V or 0; (6)Cio(OFF): 6.5pF at VO=3V or 0, OE=VCC.
