IDT74LVCH16374A 3.3V CMOS 16-BIT EDGE-TRIGGERED D-TYPE FLIP-FLOP INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVCH16374A EDGE-TRIGGERED D-TYPE FLIP- FLOP WITH 3-STATE OUTPUTS, 5V TOLERANT I/O AND BUS-HOLD DESCRIPTION FEATURES: The LVCH16374A 16-bit edge-triggered D-type register is built using Typical tSK(o) (Output Skew) < 250ps advanced dual metal CMOS technology. This high-speed, low-power ESD > 2000V per MIL-STD-883, Method 3015 > 200V using register is ideal for use as a buffer register for data synchronization and machine model (C = 200pF, R = 0) storage. The Output Enable (OE) and clock (CLK) controls are organized VCC = 3.3V 0.3V, Normal Range to operate each device as two 8-bit registers or one 16-bit register with VCC = 2.7V to 3.6V, Extended Range common clock. Flow-through organization of signal pins simplifies layout. All CMOS power levels (0.4 W typ. static) inputs are designed with hysteresis for improved noise margin. All inputs, outputs, and I/O are 5V tolerant All pins of the LVCH16374A can be driven from either 3.3V or 5V devices. Supports hot insertion This feature allows the use of this device as a translator in a mixed 3.3V/5V Available in SSOP and TSSOP packages supply system. The LVCH16374A has been designed with a 24mA output driver. This DRIVE FEATURES: driver is capable of driving a moderate to heavy load while maintaining High Output Drivers: 24mA speed performance. Reduced system switching noise The LVCH16374A has bus-hold which retains the inputs last state whenever the input goes to a high impedance. This prevents floating inputs APPLICATIONS: and eliminates the need for pull-up/down resistors. 5V and 3.3V mixed voltage systems Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1 24 1OE 2OE 48 25 2CLK 1CLK C1 C1 2 13 47 36 1D 1D 1Q1 2D1 2Q1 1D1 TO SEVEN OTHER CHANNELS TO SEVEN OTHER CHANNELS IDT and the IDT logo is a registered trademark of Integrated Device Technology, Inc.
