HD74HC243
Quad. Bus Transceivers (with noninverted 3-state outputs)
REJ03D0596–0200
(Previous ADE-205-473)
Rev.2.00
Jan 31, 2006 Description
The HD74HC243 is a noninverting buffer. Each device has one active high enable (GBA), and one active low enable (G AB). GBA enables the A output and G AB enables the B outputs. The device does not have schmitt trigger inputs. Features
? High Speed Operation: t pd = 10 ns typ (C L = 50 pF)
? High Output Current: Fanout of 15 LSTTL Loads
? Wide Operating Voltage: V CC = 2 to 6 V
? Low Input Current: 1 μA max
? Low Quiescent Supply Current: I CC (static) = 4 μA max (Ta = 25°C)
