Description

The CY74FCT257ATQCT is designed as quad 2-input multiplexer which has four identical two-input multiplexers which select four bits of data from two sources under the control of a common data select input (S).

CY74FCT257ATQCT has ten features. (1)Function, pinout, and drive compatible with FCT and F logic. (2)FCT-C speed at 4.3ns max. FCT-A speed at 5.0ns max. (3)Reduced Voh (typically=3.3V) versions of equivalent FCT functions. (4)Edge-rate control circuitry for significantly improved noise characteristics. (5)Power-off disable feature. (6)Matched rise and fall times. (7)Fully compatible with TTL input and output logic levels. (8)ESD is larger than 2000V. (9)Extended commercial range of -40°C to +85°C. (10)Sink current 64mA and source current 32mA. That are all the main features.

Some absolute maximum ratings of CY74FCT257ATQCT have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to +150°C. (2)Its ambient temperature with power applied would be from -65°C to +135°C. (3)Its supply voltage to ground potential would be from -0.5V to +7.0V. (4)Its DC input voltage would be from -0.5V to +7.0V. (5)Its DC output voltage would be from -0.5V to +7.0V. (6)Its DC output current (maximum sink current/ pin) would be 120mA. (7)Its power dissipation would be 0.5W. (8)Its static discharge voltage would be larger than 2001V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of CY74FCT257ATQCT are concluded into several points as follow. (1)Its output high voltage would be min 2.0V. (2)Its output low voltage would be typ 0.3V and max 0.55V. (3)Its input high voltage would be min 2.0V. (4)Its input low voltage would be max 0.8V. (5)Its hysteresis would be typ 0.2V. (6)Its input clamp diode voltage would be typ -0.7V and max -1.2V. (7)Its input high current would be max 5uA at Vin=Vcc. (8)Its input low voltage would be max +/-1uA at Vin=0.5V. And so on.
