IDT74FCT163952A/C 3.3V CMOS 16-BIT REGISTERED TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT REGISTERED TRANSCEIVER IDT74FCT163952A/C DESCRIPTION: FEATURES: The FCT163952 16-bit registered transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit D-type registered transceivers with separate input and output control for independent control of data flow in either direction. For example, the A-to-B Enable (xCEAB) must be LOW to enter data from the A port. xCLKAB controls the clocking function. When xCLKAB toggles from low-to-high, the data present on the A port will be clocked into the register. xOEAB performs the output enable function on the B port. Data flow from the B port to A port is similar but requires using xCEBA, xCLKBA, and xOEBA inputs. Full 16-bit operation is achieved by tying the control pins of the independent transceivers together. The FCT163952 has series current limiting resistors. These offer low ground bounce, minimal undershoot, and controlled output fall times– reducing the need for external series terminating resistors. • 0.5 MICRON CMOS Technology • Typical tSK(o) (Output Skew) < 250ps • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • VCC = 3.3V ± 0.3V, Normal Range, or VCC = 2.7V to 3.6V, Extended Range µ W typ. static) • CMOS power levels (0.4µ • Rail-to-rail output swing for increased noise margin • Low Ground Bounce (0.3V typ.) • Inputs (except I/O) can be driven by 3.3V or 5V components • Available in SSOP and TSSOP packages FUNCTIONAL BLOCK DIAGRAM 54 31 1CEBA 1CLKBA 2CEBA 30 55 2CLKBA 28 1 1OEAB 2OEAB 3 1CEAB 2CEAB 2 1CLKAB 2CLKAB 56 1OEBA 1 A1 2OEBA C CE D 5 52 2A 1 1B 1 C CE D 26 27 29 15 C CE D 42 2B 1 C CE D TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.
