SN54LVTH162373, SN74LVTH162373
3.3-V ABT 16-BIT TRANSPARENT D-TYPE LATCHES
WITH 3-STATE OUTPUTS
SCBS261M – JULY 1993 – REVISED DECEMBER 2006
FEATURES
• Members of the Texas Instruments Widebus™
Family
• Output Ports Have Equivalent 22-Ω Series
Resistors, So No External Resistors Are
Required
• Support Mixed-Mode Signal Operation (5-V
Input and Output Voltages With 3.3-V V_CC)
• Support Unregulated Battery Operation Down
to 2.7 V
• Typical V_OLP (Output Ground Bounce) <0.8 V
at V_CC = 3.3 V, T_A = 25°C
• I_off and Power-Up 3-State Support Hot
Insertion
• Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
• Distributed V_CC and GND Pins Minimize
High-Speed Switching Noise
• Flow-Through Architecture Optimizes PCB
Layout
• Latch-Up Performance Exceeds 500 mA Per
JESD 17
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)

DESCRIPTION/ORDERING INFORMATION
The 'LVTH162373 devices are16-bit transparent D-type latches with 3-state outputs designed for low-voltage
(3.3-V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment. These
devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and
working registers.
