IDT74ALVCHR16501 3.3V CMOS 18-BIT UNIVERSAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 18-BIT UNIVERSAL IDT74ALVCHR16501 BUS TRANSCEIVER WITH 3-STATE OUTPUTS AND BUS-HOLD * 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 * VCC = 2.7V to 3.6V, Extended Range * VCC = 2.5V 0.2V * CMOS power levels (0.4 W typ. static) * Rail-to-Rail output swing for increased noise margin * Available in SSOP, TSSOP, and TVSOP packages FEATURES: DESCRIPTION: DRIVE FEATURES: APPLICATIONS: * Balanced Output Drivers: 12mA * Low Switching Noise * 3.3V high speed systems * 3.3V and lower voltage computing systems This 18-bit universal bus transceiver is built using advanced dual metal CMOS technology. Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch enable (LEAB and LEBA) and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When LEAB is low, the A data is latched if CLKAB is held at a high or low logic level. If LEAB is low, the A data is stored in the latch/ flip-flop on the low-to-high transition of CLKAB. When OEAB is high, the outputs are active. When OEAB is low, the outputs are in the high-impedance state. Data flow from B to A is similiar to that of A to B but uses OEBA, LEBA, and CLKBA. The output enables are complementary (OEAB is active high and OEBA is active low). The ALVCHR16501 has series resistors in the device output structure which will significantly reduce reduce line noise when used with light loads. This driver has been designed to drive 12mA at the designated threshold levels. The ALVCHR16501 has "bus-hold" which retains the inputs' last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors.
