SHARP LH5324C00

LH5324C00
FEATURES
CMOS 24M (1.5M × 16) MROM
PIN CONNECTIONS
• 1,572,864 × 16 bit organization
• Access time: 120 ns (MAX.)
• Supply current:
– Operating: 80 mA (MAX.)
– Standby: 100 µA (MAX.)
• TTL compatible I/O
• Three-state output
• Single +5 V Power supply
• Static operation
• When the address input at both A19 and
A20 is high level, outputs become high
impedance irrespective of CE or OE.
• Package:
42-pin, 600-mil DIP
• Others:
– Non programmable
– Not designed or rated as radiation
hardened
– CMOS process (P type silicon
substrate)

NOTES:
1. X = Don’t care; High-Z = High-impedance
2. When the address inputs become HIGH to both A19 and A20, the data does not exist in this address area,
the data outputs become "High Impedance".
