74LVC244ADB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 74LVC244A/74LVCH244A 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 3.3V or 5V devices. In 3-State operation, outputs can handle 5V. These features allow the use of these devices as translators in a mixed 3.3V/5V environment.

FEATURES

• 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic

• Supply voltage range of 2.7V to 3.6V

• Complies with JEDEC standard no. 8-1A

• CMOS low power consumption

• Direct interface with TTL levels

• High impedance when VCC = 0V

• Bushold on all data inputs (74LVCH244A only)
