74LVCH32245A集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

DESCRIPTION

The 74LVC(H)32245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most

advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices in a mixed 3.3 and 5 V environment.

FEATURES

• 5 V tolerant inputs/outputs for interfacing with 5 V logic

• Wide supply voltage range of 1.2 to 3.6 V

• Complies with JEDEC standard no. 8-1A

• CMOS low power consumption

• MULTIBYTEflow-trough standard pin-out architecture

• Low inductance multiple power and ground pins for minimum noise and ground bounce

• Direct interface with TTL levels

• Bus hold on data inputs (74LVCH32245A only)

• Typical output ground bounce voltage:

VOLP<0.8VatVCC= 3.3 V; Tamb=25°C

• Typical output VOHundershoot voltage:

VOHV>2VatVCC= 3.3 V; Tamb=25°C

• Power-off disabled outputs, permitting live insertion

• Plastic fine-pitch ball grid array package.
