OCTAL BUS BUFFER

WITH 3 STATE OUTPUTS (INVERTED)

■

HIGH SPEED: t_PD= 4 ns (TYP.) at V_CC= 5V

LOW POWER DISSIPATION:

I_CC= 8 µA (MAX.) at T_A= 25 ^oC

HIGH NOISE IMMUNITY:

■

V_NIH= V_NIL= 28% V_CC(MIN.)

50Ω TRANSMISSION LINE DRIVING

CAPABILITY

SYMMETRICAL OUTPUT IMPEDANCE:

|I_OH| = I_OL=24 mA (MIN)

BALANCED PROPAGATION DELAYS:

t_PLHt_PHL

OPERATING VOLTAGE RANGE:

(Plastic Package)

(Micro Package)

ORDER CODES :

74AC240B

74AC240M

mantaining high speed operation similar to

equivalentBipolar Schottky TTL.

G control output governs four BUS BUFFERs.

This device is designed to be used with 3 state

memory address drivers, etc.

V_CC(OPR) = 2V to 6V

PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 240

IMPROVED LATCH-UP IMMUNITY

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The AC240 is an advanced CMOS OCTAL BUS

BUFFER (3-STATE) fabricated with sub-micron

silicon gate and double-layer metal wiring C²MOS

technology. It is ideal for low power applications
