74HC_HCT241_CNV_15 Datasheet, PDF (2/8 Pages) NXP Semiconductors – Octal buffer/line driver; 3-state

Philips Semiconductors
Octal buffer/line driver; 3-state
Product specification
74HC/HCT241
FEATURES
GENERAL DESCRIPTION
• Output capability: bus driver
• I_CC category: MSI
The 74HC/HCT241 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT241 are octal non-inverting buffer/line
drivers with 3-state outputs. The 3-state outputs are
controlled by the output enable inputs 1OE and 2OE.

Notes
1. C_PD is used to determine the dynamic power dissipation (P_D in µW):
P_D = C_PD × V_CC2 × f_i + ∑ (C_L × V_CC2 × f_o) where:
f_i = input frequency in MHz
f_o = output frequency in MHz
∑ (C_L × V_CC2 × f_o) = sum of outputs
C_L = output load capacitance in pF
V_CC = supply voltage in V
2. For HC the condition is V_I = GND to V_CC
For HCT the condition is V_I = GND to V_CC − 1.5 V
