74ALVCH162827

20-bit buffer/line driver; non-inverting; with 30 Ohm termination resistors; 3-state

The 74ALVCH162827 20-bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NAND output enables (nOE1 and nOE2) for maximum control flexibility.

The 74ALVCH162827 is designed with 30 Ω series resisters in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.

To ensure the high impedance state during power up or power down, nOEn should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver.

The 74ALVCH162827 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.

Features and benefits

  • CMOS low power consumption
  • MultiByte flow-through standard pin-out architecture
  • Low inductance multiple VCC and GND pins for minimum noise and ground bounce
  • Direct interface with TTL levels (2.7 V to 3.6 V)
  • Bus hold on data inputs
  • Current drive ± 12 mA at 3.0 V
  • Integrated 30 Ω termination resistors
  • Complies with JEDEC standards:
    • JESD8-5 (2.3 V to 2.7 V)
    • JESD8B/JESD36 (2.7 V to 3.6 V)
  • ESD protection:
    • HBM ANSI/ESDA/JEDEC JS-001 exceeds 2000 V
    • CDM JESD22-C101E exceeds 1000 V
