IDT74LVCH162374A 3.3V CMOS 16-BIT EDGE-TRIGGERED D-TYPE FLIP-FLOP INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVCH162374A EDGE TRIGGERED D-TYPE FLIP- FLOP WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O, BUS-HOLD DESCRIPTION: FEATURES: Typical tSK(o) (Output Skew) < 250ps The LVCH162374A 16-bit edge-triggered D-type flip-flop is built using ESD > 2000V per MIL-STD-883, Method 3015 > 200V using advanced dual metal CMOS technology. This high-speed, low-power machine model (C = 200pF, R = 0) register is ideal for use as a buffer register for data synchronization and VCC = 3.3V 0.3V, Normal Range storage. The output enable (OE) and clock (CLK) controls are organized VCC = 2.7V to 3.6V, Extended Range to operate each device as two 8-bit registers or one 16-bit register with CMOS power levels (0.4 W typ. static) common clock. Flow-through organization of signal pins simplifies layout. All inputs, outputs, and I/O are 5V tolerant All inputs are designed with hysteresis for improved noise margin. Available in TSSOP package All pins of the LVCH162374A can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. DRIVE FEATURES: The LVCH162374A has series resistors in the device output structure Balanced Output Drivers: 12mA which will significantly reduce line noise when used with light loads. This Low switching noise driver has been developed to drive 12mA at the designated thresholds. The LVCH162374A has bus-hold which retains the inputs last state APPLICATIONS: whenever the input goes to a high impedance. This prevents floating inputs 5V and 3.3V mixed voltage systems and eliminates the need for pull-up/down resistors.
