DESCRIPTION

The 74HCT244 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. G control input governs four BUS BUFFERs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED:

tPD = 15 ns (TYP.) at VCC = 4.5V

■ LOW POWER DISSIPATION:

ICC = 4μA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS :

VIH = 2V (MIN.) VIL = 0.8V (MAX)

■ BALANCED PROPAGATION DELAYS:

tPLH ? tPHL

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 6mA (MIN)

■ PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 244

M74HCT244TTR屬于集成電路（IC） > 緩沖器，驅動器，接收器，收發(fā)器。意法半導體（ST）集團制造生產的M74HCT244TTR緩沖器，驅動器，接收器，收發(fā)器邏輯緩沖器、驅動器、接收器和收發(fā)器允許隔離對某個電路的邏輯信號的訪問，以用于另一電路。緩沖器將其輸入信號（不變或反相）傳遞到其輸出，并可能用于清除弱信號或驅動負載。在布爾邏輯仿真器中，緩沖器主要用于增加傳播延遲。邏輯接收器和收發(fā)器允許在數(shù)據(jù)總線之間進行隔離通信。
