74AC16245 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS (NON INVERTED) ■ ■ ■ ■ ■ ■ ■ ■ ■ HIGH SPEED: tPD = 4.5 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 4 µA (MAX.) at TA=25°C HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) POWER DOWN PROTECTION ON INPUTS SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 16245 IMPROVED LATCH-UP IMMUNITY DESCRIPTION The 74AC16245 is an advanced high-speed CMOS 16-BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. This IC is intended for two-way asynchronous communication between data busses; the direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the busses are effectively isolated. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. All floating bus terminals during High Z State must be held HIGH or LOW. ) s ( ct TSSOP ORDER CODES PACKAGE TUBE c u d TSSOP PIN CONNECTION e t le ) s t( T&R 74AC16245TTR o r P o s b O - u d o r P e t e l o s b O July 2003 1/9 74AC16245 INPUT AND OUTPUT EQUIVALENT CIRCUIT IEC LOGIC SYMBOLS PIN DESCRIPTION PIN No SYMBOL 1 2, 3, 5, 6, 8, 9, 11, 12 13, 14, 16, 17, 19, 20, 22, 23 24 25 36, 35, 33, 32, 30, 29, 27, 26 47, 46, 44, 43, 41, 40, 38, 38 48 4, 10, 15, 21, 28, 34, 39, 45 2B1 to 2B8 Data Inputs/Outputs 2DIR Directional Control 2G Output Enable Input 2A1 to 2A8 Data Inputs/Outputs 1A1 to 1A8 Data Inputs/Outputs 1G TRUTH TABLE DIR L H X X : Don’t Care Z : High Impedance 2/9 ) s ( ct GND Ground (0V) VCC Positive Supply Voltage u d o FUNCTION t e l o s b O Output Enable Input r P e INPUTS L L H c u d 1DIR Directional Control 1B1 to 1B8 Data Inputs/Outputs 7, 18, 31, 42 G NAME AND FUNCTION A BUS B BUS OUTPUT INPUT INPUT OUTPUT Z Z o s b O - OUTPUT Yn A=B B=A Z e t le o r P ) s t( 74AC16245 ABSOLUTE MAXIMUM RATINGS Symbol VCC Parameter Supply Voltage VI DC Input Voltage VO DC Output Voltage IIK Value Unit -0.5 to +7.0 V -0.5 to +7.0 V -0.5 to VCC + 0.5 V DC Input Diode Current ± 20 mA IOK DC Output Diode Current ± 20 mA IO DC Output Current ± 25 mA ± 200 mA -65 to +150 °C 300 °C ICC or IGND DC VCC or Ground Current Tstg Storage Temperature TL Lead Temperature (10 sec) Absolute Maximum Ratings are those values beyond which damage to the device may occur.
