2 / 12 page Philips Semiconductors Product data 74ALVCHT16835 18-bit registered driver (3-State) 2 2002 Jun 05 853-2350 28376 FEATURES • Wide supply voltage range of 2.3 V to 3.6 V • Complies with JEDEC standard no. 8-1A. • CMOS low power consumption • Direct interface with TTL levels • Current drive ± 24 mA at 3.0 V • MULTIBYTETM flow-through standard pin-out architecture • Low inductance multiple V CC and GND pins for minimum noise and ground bounce • Output drive capability 50 Ω transmission lines @ 85 °C • ESD protection exceeds 1500 V HBM per JESD22-A114, A115 and 1000 V CDM per JESD22-C101 • Bus hold on data inputs eliminates the need for external pullup/pulldown resistors DESCRIPTION The 74ALVCHT16835 is a 18-bit registered driver. Data flow is controlled by active low output enable (OE), active high latch enable (LE) and clock inputs (CP). When LE is HIGH, the A to Y data flow is transparent. When LE is LOW and CP is held at LOW or HIGH, the data is latched; on the LOW to HIGH transient of CP the A-data is stored in the latch/flip-flop. When OE is LOW the outputs are active. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the latch/flip-flop. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage in V; S (CL × VCC2 × fo) = sum of outputs. |
