This device can be used as two 8-bit transceivers or one 16-bit transceiver. The 74ALVCH162245 is designed with 30Ω series resistors in both HIGH and LOW output states. 31 VCC2 VCC1 18 The 74ALVCH162245 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. 30 2A4 2B4 19 2B5 20 29 2A5 GND 21 28 GND 2B6 22 27 2A6 2B7 23 26 2A7 2DIR 24 25 2OE SW00198 QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf ≤ 2.5ns PARAMETER SYMBOL CONDITIONS TYPICAL UNIT 2.4 ns tPHL/tPLH Propagation delay An to Bn; Bn to An VCC = 2.5V, CL = 30pF VCC = 3.3V, CL = 50pF CI Input capacitance 4.0 pF CI/O Input/output capacitance 8.0 pF CPD Power dissipation capacitance per buffer Outputs enabled 27 pF Outputs disabled 4 pF VI = GND to VCC1 NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + (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; (CL × VCC2 × fo) = sum of the outputs.
