74LV241

Octal buffer/line driver (3-State)

1998 May 20

853–1925 19422

FEATURES

• Optimized for low voltage applications: 1.0 to 3.6 V

• Accepts TTL input levels between V

CC = 2.7 V and VCC = 3.6 V

• Typical V

OLP (output ground bounce) < 0.8 V at VCC = 3.3 V,

Tamb = 25°C

• Typical V

OHV (output VOH undershoot) > 2 V at VCC = 3.3 V,

Tamb = 25°C

• Output capability: bus driver

• I

CC category: MSI

DESCRIPTION

The 74LV241 is a low-voltage Si-gate CMOS device and is pin and

function compatible with 74HC/HCT241.

The 74LV241 is an octal non-inverting buffer/line driver with 3-State

outputs. The 3-State outputs are controlled by the output enable

inputs 1OE and 2OE.
