IDT74ALVCH32244 3.3V CMOS 32-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 32-BIT IDT74ALVCH32244 BUFFER/ DRIVER WITH 3-STATE OUTPUTS AND BUS-HOLD DESCRIPTION: FEATURES: This 32-bit buffer/driver is built using advanced dual metal CMOS 0.5 MICRON CMOS Technology technology. This high-speed, low power device offers bus/backplane Typical tSK(o) (Output Skew) < 250ps interface capability with improved packing density. The device has a flow- ESD > 2000V per MIL-STD-883, Method 3015 > 200V using through organization for simplifying board layout. The three-state controls machine model (C = 200pF, R = 0) operate this device in a Quad-Nibble, Dual-Byte or single 16-bit word mode. VCC = 3.3V 0.3V, Normal Range All inputs are designed with hysteresis for improved noise margin. VCC = 2.7V to 3.6V, Extended Range The ALVCH32244 has been designed with a 24mA output driver. This VCC = 2.5V 0.2V driver is capable of driving a moderate to heavy load while maintaining CMOS power levels (0.4 W typ. static) speed performance. Rail-to-Rail output swing for increased noise margin The ALVCH32244 has bus-hold which retains the inputs last state Available in 96-ball LFBGA package whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. DRIVE FEATURES: High Output Drivers: 24mA Suitable for Heavy Loads APPLICATIONS: 3.3V high speed systems 3.3V and lower voltage computing systems FUNCTIONAL BLOCK DIAGRAM A3 H4 J3 T4 3OE 1OE 5OE 7OE A5 A2 E5 E2 J5 J2 N5 N2 1Y1 3Y1 5Y1 7Y1 1A1 5A1 3A1 7A1 A6 A1 J1 N6 N1 E6 E1 J6 1Y2 5Y2 1A2 5A2 3Y2 7Y2 3A2 7A2 B2 B5 F5 F2 K5 K2 P5 P2 1Y3 5Y3 3Y3 7Y3 1A3 5A3 3A3 7A3 B6 B1 F6 F1 K6 K1 P6 P1 1Y4 5Y4 1A4 3A4 3Y4 5A4 7A4 7Y4 A4 H3 J4 T3 2OE 6OE 4OE 8OE C5 C2 G5 G2 L5 L2 R5 R2 2Y1 6Y1 4Y1 8Y1 2A1 6A1 4A1 8A1 C6 C1 G1 L6 L1 R6 R1 G6 2Y2 6Y2 4Y2 8Y2 2A2 4A2 6A2 8A2 D2 M5 M2 D5 H6 H1 T6 T1 2Y3 6Y3 4Y3 8Y3 2A3 4A3 6A3 8A3 M6 D6 D1 H5 H2 M1 T5 T2 2A4 2Y4 4Y4 6A4 6Y4 4A4 8A4 8Y4 IDT and the IDT logo are registered trademarks of Integrated Device Technology, Inc.
