Part Details:

74LCX646 February 1994 Revised March 2001 Low V 74LCX646Low Voltage Octal Transceiver/Register olt with 5V Tolerant Inputs and Outputs age General Description Features Oct The LCX646 consists of registered bus transceiver circuits, s 5V tolerant inputs and outputs D-type flip-flops, and control circuitry providing multiplexed s 2.3V - 3.6V V a CC specifications provided transmission of data directly from the input bus or from the l T s internal storage registers. Data on the A or B bus will be 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max r loaded into the respective registers on the LOW-to-HIGH s Power down high impedance inputs and outputs an transition of the appropriate pin (CPAB or CPBA) (see s Supports live insertion/withdrawal (Note 1) sceiv Functional Description). s ±24 mA output drive (VCC = 3.0V) The LCX646 is designed for low voltage (2.5V or 3.3V) VCC s Implements patented noise/EMI reduction circuitry applications with capability of interfacing to a 5V signal e environment. s Latch-up performance exceeds 500 mA r/ s ESD performance: R The LCX646 is fabricated with an advanced CMOS tech- e nology to achieve high speed operation while maintaining Human body model > 2000V gist CMOS low power dissipation. Machine model > 200V Note 1: To ensure the high-impedance state during power up or down, OE er wit should be tied to VCC through a pull-up resistor: the minimum value or theresistor is determined by the current-sourcing capability of the driver. h 5V T Ordering Code: Order Number Package Number
