General Description
The HD74ALVCH16270 is used in applications where data must be transferred from a narrow high speed bus to a wide lower frequency bus.
The device provides synchronous data exchange between the two ports.
Key Features
- VCC = 2.3 V to 3.6 V.
- Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
- Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
- High output current ±24 mA (@VCC = 3.0 V).
- Bus hold on data inputs eliminates the need for external pullup / pulldown resistors HD74ALVCH16270 Function Table Inputs CLK ↑ ↑ ↑ ↑ OEA H H L L OEB H L H L Outputs A Z Z Active Active 1B, 2B Z Active Z Active Output enable Inputs CLKENA1 L L L L H H H CLKENA2 H H L.
