CMOS OCTAL BUS TRANSCEIVER/REGISTER WITH 5 VOLT TOLERANT INPUTS AND OUTPUTS(3-STATE) s 5V TOLERANT INPUTS AND OUTPUTS s HIGH SPEED:tPD = 7.0 ns (MAX.) at VCC = 3V s POWER DOWN PROTECTION ON INPUTS AND OUTPUTS s SYMMETRICAL OUTPUT IMPEDANCE: SOP TSSOP |IOH| = IOL = 24mA (MIN) at VCC = 3V s PCI BUS LEVELS GUARANTEED AT 24 mA Table 1: Order Codes s BALANCED PROPAGATION DELAYS:tPLH tPHL PACKAGE T & R s OPERATING VOLTAGE RANGE:V SOP 74LCX652RM13TR CC(OPR) = 2.0V to 3.6V (1.5V Data Retention) TSSOP 74LCX652TTR s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 652 This device consists of bus transceiver circuits s LATCH-UP PERFORMANCE EXCEEDS with 3 state, D-type flip-flops, and control circuitry 500mA (JESD 17) arranged for multiplexed transmission of datadirectly from the input bus or from the internal s ESD PERFORMANCE: HBM > 2000V (MIL STD 883 method 3015); storage registers. Enable (GAB) and (GBA) pins MM > 200V are provided to control the transceiver functions. Select AB and Select BA control pins are providedto select whether real-time or stored data is DESCRIPTION transferred. A low input level selects real-time, The 74LCX652 is a low voltage CMOS OCTAL and a high selects stored data. BUS TRANSCEIVER AND REGISTER Data on the A or B bus, or both, can be stored in (3-STATE) fabricated with sub-micron silicon gate the internal D flip-flop by low to high transitions at and double-layer metal wiring C2MOS technology. the appropriate clock pins (CAB or CBA) It is ideal for low power and high speed 3.3V regardless of the select or enable control pins.
