NOTES: 1. Applies for external input and bidirectional buffers. V_I > V_CC does not apply to fail-safe terminals. PCI terminals are measured with respect to V_CCP instead of V_CC. PC Card terminals are measured with respect to V_CCA or V_CCB. ZV terminals are measured with respect to V_CCZ, and miscellaneous signals are measured with respect to V_CCI. The limit specified applies for a dc condition.

The TI PCI1251A is a high-performance PC Card controller with a 32-bit PCI interface. PCI1251A supports two independent PC Card sockets compliant with the 1997 PC Card Standard. The PCI1251A provides a rich feature set that makes it the best choice for bridging between PCI and PC Cards in both notebook and desktop computers. The 1997 PC Card Standard retains the 16-bit PC Card specification defined in PCMCIA Release 2.2, and defines the new 32-bit PC Card, CardBus, capable of full 32-bit data transfers at 33 MHz. The PCI1251A supports any combination of 16-bit and CardBus PC Cards in the two sockets, powered at 5 V or 3.3 V, as required.

The PCI1251A is compliant with the latest PCI Bus Power Management Specification. PCI1251A is also compliant with the PCI Local Bus Specification 2.2, and its PCI interface can act as either a PCI master device or a PCI slave device. The PCI bus mastering is initiated during 16-bit PC Card direct memory access (DMA) transfers or CardBus PC Card bridging transactions
